Joomla HTTP 500 update error

How to resolve Joomla HTTP 500 error after updates? Over the last week we, at Vevida, received quite a lot problem reports by customers who updated Joomla to Joomla version 3.2.0. After logging on to their administrator back-end, they received an HTTP 500.0 error with error code 0x8007000d. Let’s investigate and resolve this Joomla Administrator login HTTP 500 error.

Fix Joomla HTTP 500 error after updating

Luckily the error is quite easy to fix. If only I knew this earlier, it would have saved me some time :).

  1. when you’ve tried to log on and the HTTP 500.0 error is displayed, add ?option=com_installer&view=database in the address bar of your browser to the URI. The full URI then becomes http://www.example.com/administrator/index.php?option=com_installer&view=database.
  2. after pressing the ENTER key on your keyboard, you’re automatically logged on to your Joomla 3.2.0 administrator back-end.
  3. You’ll probably notice database errors. These database errors can be repaired in the back-end using the Fix-button, and this resolves the log in issue permanently

Incorrect file permissions on log/error.php

Turns out, at least on Windows Server IIS, PHP/FastCgiModule throws this 0x8007000d error when file and directory permissions are incorrectly configured. However, at the same time -after setting correct file permissions on logs/error.php and logging in- Joomla complained about two database problems:

Database schema version (3.1.1) does not match CMS version (3.3.6-2014-09-30).
Database update version (None) does not match CMS version (3.3.6).
