This happened for the first time for a short while yesterday. It wasn’t possible to connect to the forum at all, a blank page with this message comes up.
phpBB Critical Error - cannot connect to the database
It came back up for the rest of the day, but it’s happening again today.
I didn’t make any kind of modification to it at all, so I thought it might be something to do with the server (…?) I have no skill in this area and would appreciate very much if someone could tell me how to fix this or what might be causing it.
