Hello Community,

I’m looking for few days for an answer. I had to backup my working OpenProject instance of my vServer. I run the backup command. Everything works. I tried to restore this at a local VM, everything works.

When I tried to restore this on my new vServer, nothing works. I can reach the login page, but then I get an “Internal Error”. I read the log-files, but I have no answer what the problem is. Maybe someone can give me some hints…

In my opinion there must be something wrong with the MySQL Database (?), but I have no idea, how to fix this?

Can someone help me?

Thank you
