You're likely reading this because your Joomla site has had some sort of fatal error and given you a message similar to the above.

There are two likely reason for this:

  • A system plugin is causing failures on your site
  • A change has been made to your host (e.g. a PHP version upgrade that isn't compatible with an extension or Joomla itself if you are running an old version)

How to resolve

If you've made any recent changes to your system plugins disable the system plugins one by one in the database until you find which one is responsible (remember you should not need to disable any core Joomla system plugins).

edit /configuration.php

Change

$debug = false;

to

$debug = true;

save the file and then reload the error page. This will then give you the REAL error message and a debug stack trace to help identify the root cause of the problem
