Cannot make any backend changes - 500 error

Post by caseyben » Sat May 15, 2021 5:45 pm

I cannot make any changes to my Joomla site. Whenever I attempt to make changes, I get this error:
An error has occurred.
0 Call to undefined function Connection timed out()

This happens when I save articles, save configurations, publish/unpublish articles, update plugins, etc.

The tawkto plugin is not compatible with the version of php you are running. Disable it or get an update.

I don't know if it has anything to do with your 500 but your version of plg_system_tawkto seems to be outdated. The current version shouldn't show this deprecated message.

https://github.com/tawk/tawk-joomla/releases/tag/3.0.2

Concerning the rest. Try:
- Open file configuration.php after you've set write permissions to 644.
- Change following lines as follows:

Code: Select all

public $error_reporting = 'maximum';
public $debug = '1';
- Look if the error message then contains a "Call Stack" that you can post here.
- Don't forget to reset the two lines afterwards.

After enabling debugging, I was able to see which plugin was causing the error. Thank you very much! (It was an unused plugin called jSGCache)
