oh wow, looking at the amount of replies on this forum i guess it is not likely help is comming. Anyone know where I can get help with a bigger userbase?

tried 3 times to update and every time it blows up my backend with this fatal error. Have to roll back all plugins via database and reactivate all just to roll back this patch.
Can someone decipher whats going on here?
