This is a workaround to remove a creator from a facebook fanpage!
Facebook has acknowleged this as a bug and is trying to fix it – so you can either wait till there is a official solution or use this workaround.
Make sure you have appointed others to take over the administrator duties, as otherwhise your rely on facebook “support”
Step 1: Remove yourself as a fan of that page
Step 2: Deactivate your account for at least an hour
Step 3: Activate again and you are no longer founder or administrator of that page
Credits go to this guy
Update: Since this is only a “dirty” work around which apparently does not work for all fanpages, I’ve started a Page on Facebook (how ironic) to adress this problem!
