Two to three days the message is "Internal Servier Error" and nothing else appear on the page. Why?

Internal Server Error

This message appear on the otherwise normal working website and have been like that for two-three days. Why? We haven’t changed anything.

Hello @rolfsleimann

I’ve responded to the ticket that you’ve created to request for more information.

Hi Grace_cf,
I have sent the screenshot of the error message already when I created this ticket. Haven’t you seen it?
