This appears when I try to save changes to a usergroup.

It also does not save the changes although it says it's done successfully..

Deactivate all products/plugins you have loaded and try again.

Yeah deactivating them just causes sql errors..

EDIT: Alright well i enabled them all again, and now it works.. >_<
