It turns out that it was a server option that there was something wrong with. After I deleted it and created it again, everything works.

I get the same error message. How did you find out what server option was 'wrong'?

I found out that I had manually entered the same option for both the scope and the server. After I removed it from the scope, it appeared as a server option and everything worked fine.
