We're sorry, but a temporary technical error has occurred which means we cannot display this site right now.

What do you mean by all credentials on file are correct? I'm not the main account owner. I can't submit a ticket from our actual website because it's down...

The first thing you should check when receiving an Internal Server Error is whether one of the following is the cause:

    Invalid file or directory rights;
    Incorrect directives in a .htaccess file;
    The script runs more than 60 seconds with 100% CPU usage.

Problem is I don't have access to the back end server.

It was working yesterday just fine. Can you give instructions on how to check those causes above?

If you have ftp access, download and check the htaccess file as well as the permissions files and directories.

...or contact the host. Another site may have overloaded your server, or dDos attack

If you were switching php versions, or if using in cpanel, make sure you set memory_limit allocation to that specific php version and check other allocations.

Looks like the issue was in the PHP-FPM being enabled in WHM. Any idea why this would be?

In the cPanel & WHM 76 version and later, the cPanel system enables PHP-FPM by default on a newly installed cPanel server.
