A new error on my website occured. I think I did not make any changes that could cause this problem.

I can login in admin normally and then when I click on everything except installed components there is 500 server error. In error logs I can find nothing about it.

Any sugestions please?

Thank you! Filip

  • What version of Joomla are you using? – Lodder Dec 25 '15 at 19:40
  • I use version 3.4.1 – Filip Dec 26 '15 at 7:28
  • By staying on 3.4.1, you're leaving yourself vulnerable to 2 very important security issues that have arisen recently. Please update to 3.4.8 immediately. – Lodder Dec 26 '15 at 10:49

Some things to try (assuming you can get to some or all of these pages):

  • update to the latest version of Joomla (if you haven't already)
  • update third party extensions to the latest versions
  • switch to the alternative admin template to see if the issue is template related
  • check if you have any third party administrator modules installed and if so, temporarily disable these to see if this helps
  • similarly, check what third party plugins are installed and temporarily disable these to see if this helps

Some other things to try are:

  • rename your .htaccess file to .htaccess.old and copy the default htaccess.txt to .htaccess to test if the issue may be caused by something in your .htaccess file
  • temporarily disable Search Engine Friendly URLs and URL Rewriting to see if this helps (if you can't get to Global Configuration in the back-end, edit the configuration.php file and set public $sef = '0'; and public $sef_rewrite = '0';
  • back up your website and try running the "Reinstall Joomla core files" option in Components -> Joomla Update

Also check with your hosting company whether they have any ideas (e.g. could mod_security be causing this?).

If you are using Linux, make sure installed components have correct permissions.
