[Solved] NextCloud 12 Can’t Access Admin Pages – Internal Server Error

If you are running NextCloud version 12 and you cannot reach the “Admin” area of the Web GUI because you receive an error message page that states that an Internal Server Error has occurred, here is a solution to this problem that worked for me.

Solution:  Try disabling and “removing” the OnlyOffice App.  Merely disabling the OnlyOffice App did not help.  Login as a user with administrative privileges, go to Apps, go to “office and text” apps category page, and click the “remove” link under the “OnlyOffice” app.  Now, go to the admin area and you will be granted access to the admin console area pages.

Not to worry.  The OnlyOffice selection will remain in the apps area.  When you click the button to “Enable” OnlyOffice, the enabling process will automatically download / import the necessary files (to connect NextCloud to your physically separate OnlyOffice server) that were previously removed.  


I had installed Nextcloud version 11 on Ubuntu 16.04 and PHP 7.x without issue and within a few days received an update to Nexcloud version 12 which update I applied and it has been working fine.  I first tried to install OnlyOffice and later tried to install Collabora Online, neither of which worked for me, so I scrapped the idea of using those apps, and I disabled both Apps in the Apps management area of the Nextcloud Web GUI.   However, I recently noticed that I cannot access the Admin Console pages in the web GUI. Everything else in the Nextcloud web GUI can be accessed without error messages, but when I select “Admin” I get the following error message:

Internal Server Error
The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

The same issue and solution were found with the OnlyOffice App in NextCloud Version 11 as well. See:

Remove the Tab to Open Microsoft Edge in Internet Explorer of Windows 10

Starting with Windows 10 build 15002, a new tab called “Open Microsoft Edge” has been added to the tab bar of Internet Explorer.  This Edge Tab is situated next to the New Tab button on the Tab Bar.

This article will show you how to remove this Open Microsoft Edge Tab.

1. Click/tap on the Tools (Alt+X) button in Internet Explorer, and click/tap on Internet Options. (see screenshot below)


2. Click/tap on the Advanced tab in Internet Options, check (remove) or uncheck (default add) the Hide the button (next to the New Tab button) that open Microsoft Edge option under the Browsing section for what you want, and click/tap on OK. (see screenshot below).  Click Apply button, Click OK.

3. Close and reopen Internet Explorer to see that the change has been applied and that the unwanted Tab is gone.

Bye the way, Microsoft wants you to use the Edge browser because all of your searches and your browsing habits are stored to the BING CLOUD.  Microsoft can use your browsing habits to serve you targeted ads in Microsoft Edge.  So far, Microsoft has not chosen to do this when you use Internet Explorer.  I recommend disabling Edge to the maximum extent possible.  Don’t use the Windows 10 apps for “Contacts” or “Mail” or Calendar.  All the content of these Windows 10 Apps is sifted by Microsoft and the content is stored in the Bing Cloud.  Don’t use Cortana.  Same reasoning.  Disable it until it only serves as a file search box.  Finally, go into “Start,” “Settings,” and “Privacy,” and turn OFF as much information leaking functionality as possible, which would otherwise allow apps and Microsoft Windows 10 to store and use your personal information, and the personal information of your contacts, business associates, clients, etc.  Never Log into Windows 10 with your Windows Account ID.  Never authorize the use of your Windows Account ID as the default configuration.  As soon as you enable an APP from the Windows App store, you will be asked to make that default authorization.  You might skip right past it.  That is their intent. 

Allow Remote Desktop for Administration on Windows Server 2008 R2

Using Remote Desktop

Applies To: Windows Server 2008 R2

To allow remote connections for administrative purposes only, you do not have to install the RD Session Host role service. Instead, you enable Remote Desktop on the computer that you want to remotely administer.

Remote Desktop supports only two concurrent remote connections to the computer. You do not need Remote Desktop Services client access licenses (RDS CALs) for these connections.

You can use the following procedure to enable Remote Desktop on a Windows Server 2008 R2 computer.

Membership in the local Administrators group, or equivalent, on the computer that you plan to configure, is the minimum required to complete this procedure.

To enable Remote Desktop

  1. Start the System tool. To start the System tool, click Start, click Run, type control system and then click OK.
  2. Under Tasks, click Remote settings.
  3. In the System Properties dialog box, on the Remote tab, click either of the following, depending on your environment:
    • Allow connections from computers running any version of Remote Desktop (less secure)
    • Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)

    For more information about the two options, click the Help me choose link on the Remote tab.

  4. Click Select Users to add the users and groups that need to connect to the computer by using Remote Desktop. The users and groups that you add are added to the Remote Desktop Users group.
    Members of the local Administrators group can connect even if they are not listed.


Install Apache, PHP and MySQL on Windows Server 2008 R2 SP1

 Apache doesn’t provide binaries for Windows, however Apache provides links to several third-party sites that do provide binaries, for example, Apache Lounge. From the Apache Lounge website, and depending on your Windows Server version (32bir-x86 or 64bit-x64 ) we can download either the 32-Bit version (win32) or the 64-Bit one (Win64)

Download the Prerequisites – Example: 64bit versions:

Go to Apache Lounge: Apache2.4.25-win64-VC14
The File Download: (

Go to  PHP-7.1-VC14-x64-Thread-Safe
The File Download: (

Find this at Microsoft:
C++RedistributableVisualStudio2015 (vc_redist.x64.exe)

Installation Instructions for Apache:

First Install the C++ Redistributable Visual Studio 2015.  It will show up in your Programs and Features in the Control Panel.  Using the PHP-7.15 VC14 x64 thread safe and the Apache2.4.25-Win64=VC14, you should also use the C++ VS2015 x64 redistributable (rather than VS2017 version).  Make everything match or you will have errors when you try to start Apache after you

Unzip the Apache2.4.25 VC14 and then copy the extracted contents to a new folder c:/Apache24 (that is the ServerRoot in the config).
Default folder for your your web pages is DocumentRoot “c:/Apache24/htdocs”

Note: If  you unzip to a location other than C:\Apache24, you will need to change ServerRoot in the httpd.conf, and also change in httpd.conf the Documenroot, Directories, ScriptAlias, also when you use the extra folder config file(s) change to your location there.

We may need to set up a fully qualified domain name at this point.

Starting Apache in a DOS box as Administrator.  In other words, ppen a command prompt “As Administrator.”

Change the directory as follow:

C:\apache24\bin> httpd.exe

At this point, It may appear to you that the system is hanging, but it is NOT hanging.  In fact, it means there are no errors, at least those that are reported at the moment, and that Apache is probably started and running.  Test Apache by opening a web browser and typing localhost in the address bar. Hit enter.  “IT WORKS!”

To “Break” from the “Hang” in the DOS command prompt:
C:\apache24\bin> Ctrl+C

After you install PHP7, then come back here and
Install Apache as a service:

C:\apache24\bin> httpd.exe -k install

Installation Instructions for Installing PHP7.1.5:

Using Windows Explorer (file explorer), create a new folder named php at the Windows C: drive root:


Now, extract all the folders and files from

Then copy those extracted folders and file contents to the new folder:

Now, go get and install Notepad++ if you have not already installed it.  This text editor (or one like it) is a must to open and edit various text configuration files for php and apache, etc.

Here is the download page for Notepad++:  Get the 64-bit or 32-bit version of Notepad++ that your system requires:

But, here is the installer file for the 64-bit version of Notepad++

Within the php root c:\php, open the php.ini.production file and save it as a file named php.ini in the root folder c:\php

Using Windows Explorer (file explorer) find the file called php.ini.production.  Open it using Notepad++ editor.  Now, on the Notpad++ menu, click File, select SAVE AS and change the name of the file to php.ini before saving it. 

APPEND the following items to the existing items within the “PATH” System Environment Variable. Note a Semicolon ; must separate each path item.  If you don’t know how to do this, you must learn.


Go to a Dos command prompt and type in:

path (press enter)

You will see a display of what is in the current path. At this point, the above-appended path items are not yet included in the current path.

Log Off Windows, then Ctrl-Alt-Del and log into Windows again.

Now, open a command prompt and type:

path (press enter)

You will see the existing path containing the above-appended path items. 

Integrate / Connect Apache2 to your PHP7:

Using Windows Explorer, go to c:\apache24\conf

Open with Notepad++ the file called httpd.conf
Scroll down within the httpd.conf file and just below all the “LoadModule” lines, insert the following new lines:

LoadModule php7_module C:/PHP/php7apache2_4.dll

<IfModule php7_module>
DirectoryIndex index.html index.php
AddHandler application/x-httpd-php .php
PHPIniDir “C:/PHP”

Save the changes to httpd.conf file and then close Notepad++

Log off Windows, and log into Windows again.

Test Apache now having php referenced from the httpd.conf of Apache.  How, just like we did above.

Start Apache in a DOS box as Administrator.  In other words, open a command prompt “As Administrator.”

Change the directory as follow:

and type httpd.exe at the prompt (and press enter).

C:\apache24\bin> httpd.exe

If it “hangs” without errors, you are good!  Open a browser and input localhost in the address bar.  IT WORK! 

In the command prompt window, enter Ctrl+C in order to break to the C:\> prompt.

In Windows, click Start, point at Administrative Tools, and select Services.  Then, in the Services list, find the Apache service near the beginning of the list, right-click the Apache service and left click /or select Properties. Find the correct TAB to STOP the Apache service.

Remember that I said above, after you install PHP7, then come back here and

Install Apache as a service:

C:\apache24\bin> httpd.exe -k install

Test localhost in your Web Browser.  IT WORKS!

Displaying PHP INFO:

Open Notepad++ text editor and create a new file (on the menu, click file, new).  Now, save the new with a filename of phpinfo.php

While you still have the new “phpinfo.php” file displayed within Notepad++, now insert the following contents on line 1 of the new file.

<?php phpinfo() ; ?>

Save the file named phpinfo.php with only this one line of content.  Copy or save this file to the root folder of the Apache http docs. In other words, save or copy the new phpinfo.php file into the following target sub-folder.


Open a web browser, type into the address bar:



Open TCP Port 80 In Windows Firewall

Open TCP Port 443 in Windows Firewall the same way.

Configure httdd.conf using Notepad++

Find httpd.conf in C:\apache24\conf\
#Insert next line & change svr (host header domain com or net)
ServerName svr.yourdomain.tld

Restart Apache service in the Services Module
Start, Administrative Tools, Services.

Set Up a DNS Entry — “A” (Address) record, pointing to your server’s fully qualified domain name and the IP address

You should now be able to connect from a remote

Double click ApacheMonitor.exe, or put it in your Startup folder.

How to Identify and Stop and Remove a Docker Container

This pertains to Ubuntu Server 16.04 running Apache2.x, PHP7.x, and MySQL.  NextCloud 12 is installed and running on a domain with an SSL certificate issued by a public CA (on www.mydomain.tld and mydomain.tld).  I tried to integrate Collabora (Docker) obtaining its own SSL on a subdomain (office.mydomain.tld)

It became necessary to remove and reinstall the Collabora docker container / image. My two SSL certificates were conflicting after Collabora was installed and enabled in NextCloud 12. There was a failed configuration when I following the guided instructions for integrating Collabora online with NextCloud.  Incidentally, the installation mistake occurred  during the “run” phase. I mistakenly (and understandably) entered the sub-domain “office.mydomain.tld” (i.e. the subdomain where my collabora SSL certificate will address) rather than entering the already configured nextcloud domain www.mydomain.tld.  See the correct run command at the end of this Article.

Open terminal or putty ssh connection:

To See All docker containers:
sudo docker ps -a

To Stop a running docker container:
sudo docker stop <container id>
sudo docker stop 94fc7ad48626

Check the status again:
sudo docker ps -a

To Remove a stopped docker container:
sudo docker rm <container id>
sudo docker rm 94fc7ad48626

If there is an error at the removal step, it may be necessary to either restart apache or reboot the system.  Restarting Apache did not work for me.  I rebooted the system.

After reboot, check the status again and the container ID should be gone/empty. CONGRATULATIONS.  

When you reinstall Collabora:

Example to run the docker container referencing correct sub-domain of the previously installed nextcloud:
sudo docker run -t -d -p -e ‘domain=nextcloud\\.your-domain\\.com’ –restart always –cap-add MKNOD collabora/code

I am not sure whether I should again first pull the docker Collabora/code before the docker run.  I will let you know.

Remove ‘Powered By’ in Footer of Septera Theme by CryoutCreations

If you make this edit, please understand that you should either pay Cryout Creations $25 for support (and CC’s removal of their part of this “Powered By WordPress” footer segment), or please insert authoring credit for Cryout Creations elsewhere on your website for their development of this Septera theme.

First, on you website, locate the core.php file in the path wp-content/themes/septera/includes/

Next, create a backup of the original core.php file by copying this file to a location outside your website.  Then, come back and make your changes to the core.php file that is live online from your website. Understand that If you do not self-host your website on you own server, thus having direct access to the server file system and this core.php file, then you will likely need to access it via ftp to make a backup, perform the edit, and overwrite the original online file with your edited file.

You can edit the core.php file using a good text editor, such as the Notepad++ editor.  In core.php first locate the Footer Hook section from lines 235 to 248.  Insert //Rem at the beginning of those certain 4 lines (to disable them) as shown below:

* Footer Hook
add_action( ‘cryout_master_footer_hook’, ‘septera_master_footer’ );
function septera_master_footer() {
$septera_theme = wp_get_theme();
do_action( ‘cryout_footer_hook’ );
echo ‘<div id=”footer-separator”></div>’;
echo ‘<div id=”site-copyright”>’ . wp_kses_post( cryout_get_option( ‘septera_copyright’ ) ) . ‘</div>’;
//REM echo ‘<div style=”display:block;float:right;clear: right;font-size: .85em;font-weight: bold; text-transform: uppercase;”>’ . __( “Powered by”, “septera” ) .
//REM ‘<a target=”_blank” href=”‘ . esc_html( $septera_theme->get( ‘ThemeURI’ ) ) . ‘” title=”‘;
//REM echo ‘Septera WordPress Theme by ‘ . ‘Cryout Creations”> ‘ . ‘Septera’ .'</a> &amp; <a target=”_blank” href=”‘ . “”;
//REM echo ‘” title=”‘ . __( “Semantic Personal Publishing Platform”, “septera”) . ‘”> ‘ . sprintf( ” %s.”, “WordPress” ) . ‘</a></div>’;

Click to expand the following screen capture image to see what this section looks like from within the Notepad++ editor.

footer hook in core.php

I tried using a child theme to make this change, but I was having some problems making it work.  This may have something to do with the priority of functions loading (i.e. the order in which functions are loading) between the child and parent themes. I changed some priorities in the add_actions and do_action of the child theme, but to no avail.  Let me know if you figure it out.  Send comments.  sheldon @

Alternative way to make the same change.   You could also edit the core.php theme file from within the WordPress administrative dashboard.  On the dashboard menu, point at “Appearance” and select “Editor.”  Scroll down the file list on the right side of the editor page and select “core.php.”  //REM out the same 4 lines in the footer hook section as shown in the following screen image.  And click the update save button to save your changes.

Fix Error: Google Chrome Profile Could Not Be Opened Correctly

Here is the fix: In Windows 10, open Windows File Manager (Windows Explorer). Make sure that you configure folder options to display hidden files and folders.

Follow this path:

  • This PC
  • Local Disk (C:)
  • /Users
  • /(Your Username)
  • /AppData
  • /Local
  • /Google
  • /Chrome
  • /User Data
  • /Default

Scroll Down within the /Default folder and Find and Delete the file called “Web Data.”

You may be restricted from deleting the “Web Date” file because it is in use by Google Chrome processes.  In this case, you will first need to stop all the Chrome processes and add-ons sub-processes.  Close each Chrome browser window.  Click simultaneously the keys, CTRL + ALT + Delete. Then, select task manager.   Select the Processes tab.  On the left menu under “Apps,” if any Chrome browser windows are still open, you will need to expand the Google Chrome (32 bit) app/s, right click each Chrome Page or Tab that you find in the list, and left click “end task.”  This should close all open Chrome pages and tabs.  Under “Background Processes” in the left menu list, just right-click each Google Chrome (32 bit) sub-process, and Left click to select “End Task” for each.  Now, you can proceed to delete the “Web Data” file.

Exchange 2010 Management Console Failed

The Oxford SBS Guy explains that he encountered a problem and received an error message while attempting to open Microsoft Exchange 2010 Management Console.  He determined that one way to correct this problem is to open a command prompt and perform an iisreset.

Here is then entire error message that Oxford SBS Guy received while trying to open the Exchange 2010 Management Console:

“The attempt to connect to http://server/Powershell user ‘Kerberos’ authentication failed: Connecting to remote server failed with the following error message: The WS-Management service cannot process the request. The system load quota of 1000 requests per 2 seconds has been exceeded. Send future requests at a slower rate or raise the quota for this user. The next request from this user will not be approved for at least xx milliseconds.”
