Re: Search for members not working
If by older do you mean imported from an existing MU install?
I suspect so, and this has been covered before. For BuddyPress to “see” users, they need to update at LEAST the “fullname” field in their user profile.
I think I am going to do two things to help alleviate this problem.
1.) Edit the codex to mention this in a “conversion/MU Import” section.
2.) Make a plugin to update all user info that doesn’t already have it there, as well as clean up the login name in the event it was a port from wp.org to wpmu. (Not sure why wp.org allows spaces and symbols in usernames, but mu does not. Seems silly to handle them differently between sister platforms.)
