500 Internal Server Error message when install Joomla module

I recently bought Deluxe Windows Hosting with Plesk.

I installed Joomla 3.8.8 from Plesk.

Joomla installation seems to work.

But, when I try to instal any Joomla modules or plugins, I get allways 500 Error message:

"Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error.

More information about this error may be available in the server error log."

The modules and plugins are common used ones (e.g.: JCE editor, K2, etc.).


Do you have any idea how could I solve this issue?

Thanks in advance for your help!




Hi @Fogi, thanks for posting.

A 500 internal server error is a generic error message and it's difficult to say what the issue might be without any other info. You might want to check out this article on how to enable detailed error messages on Plesk hosting, and then use that information to troubleshoot the issue further:
