I’m experiencing this too. Running BP 1.2.1, WPMU 2.9.1, PHP Version 5.2.9-2, Apache 2.2.11 (Win32). On the previous version, the Who’s Online work perfectly, on the current version, I just get the annoying “There are no users currently online”.
I know that there are at least 16 people online, but for some reason, they are not displayed. I Google’d for a solution, but have not (up to now) found anyone experiencing this with the new version.
I’m experiencing the same two issues ( alphabetical list does not list any users, and the message ‘No members found. Members must fill in at least …..’)
The member search facility on the Members page also does not work for me.
Using WordPress MU 2.8.4 + BP 1.0.3. Clean install, have never re-installed or deleted anything off the site yet.
One thing that ‘may’ make a difference is that I’m running Normal WordPress as my main, publicly viewable site, and the WordPress MU in a subfolder off the root. The database table names are different though, so I doubt there’s a conflict. For the standard WordPress install I used ‘wp2_’ as the table prefix.
