I had chossen the Style "Blue 2" in my profile (UCP) as board style. But the problem is, that while using Blue2, I can't make changes in the UCP>>Board Preferences>>Edit Global Preferences, because I wanted to change the style or change for example "Hide online status", but by submitting the form I get every time - and it doesn't metter how often I submitted the form or what subject i changed - the error "The submitted form was invalid. Try submitting again."
I had nothing changed at the templates or in the ACP that belongs to Blue 2.

Edit: I get the same Error "The submitted form was invalid. Try submitting again." while trying to make a post or to edit a post while using Blue2
