BuddyPress.org

Hi @imath
Thank you for your support, as you wrote above the problem was in the template! I fixed it as recommended and everything worked!

I want to add that today I managed to test two dozen third-party plugins and half of them stopped working properly with the 12.0.0 update, so the problem is not with BuddyPress but with third-party developers who have not prepared for this update!
