I believe there is a bug.
In order to use Membership you must disable user registration. When using Ultimate & Membership, users can still register without being a member.
Soo…that is how I have it set-up. User reg is disabled and it says that on the wp-signup page. But users can still register through the FB Connect part of the plugin. They become ‘inactive’ members.
I want to allow the FB connect for my members, but not open it up for inactive members.
