When viewing Network Admin > Users, I can see in the far right column what sites each user is a member of. Also, when viewing Network Admin > Sites, I can see in the far right column which users are a member of that site.
However, when I go to my main site (and only on the main site) Users > All Users I see zero users assigned to it. I downloaded and activated the Add Multiple Users plugin in hopes of assigning all the existing users to the main site again. After I assigned them again using this plugin, I still can't see any users on my main site.
I tried using the Multisite User Management plugin to assign roles to all of my users. When I visit the Network Settings page to set up the default role assigned to users, I see zero roles in the dropdown box next to my main site. So, apparently there are no roles for my site either (??).
Caveate: I just upgraded to 3.3.2. Thinking that might be the problem, I switched to my backup of 3.3.1, but my backup is having the same issue, so I have gone back to 3.3.2 again.
What do I need to check in my database to get this resolved?
