Good afternoon,
We have problems logging into the customer panel.
https://www.domainname.com/osTicket/login.php
HTTP ERROR 500
This error appears suddenly.
Recently our DNS service provider made a server change, but they don't support me for this thread.
I'm losing with programming and I can't get the program to work.
In the error.log only this appears, I do not see the sense.
