Permission Problem after upgrading
Upgrading from 2.0.14 to 188.8.131.52. When logged in as anyone but the #1
account including administrators with all permission check boxes checked I get an error saying 'permission problem' You dont have permission to do that when clicking on my own or anyone else profile as well as the activity section. Utility/update ran successfully and I have disabled all plugins to no avail. Something weird is happening with permissions.
