BuddyPress.org

Hello. When I am not logged in to my wp site and I view a user profile, their avatar appears on the profile. When I login as admin and view a user profile, my admin avatar appears on their profile. I just noticed this and don’t know when this took effect. I am currently running BP 1.5.4
I also get this message: You’ll need to activate a BuddyPress-compatible theme to take advantage of all of BuddyPress’s features. We’ve bundled a default theme, but you can always install some other compatible themes or update your existing WordPress theme.

Any help appreciated.
