Yes that's what I meant

[provokateurin]

Can you check your logs for any other errors and post them? Also please try to restart your web server and database, it might fix the problem already.

[seals187]

we rebooted DB, webserver and server itself, but that didn't helped.
Actually we have some other errors, but not for that particular problem with the teamfolder app I think.
