Since upgrading to the from 2.5.2.7 to the latest version we have a had a very annoying problem. We can’t update any user with directly editing the database. If I go to Subscribers, select a user and modify their Preferences it will completely block me out of the wordpress admin section and break that session of wordpress until I wipe the cookies. I have tried disabling all other plug-ins to see if it was a conflict but can’t come up with anything to resolve it. Any ideas?
