unfortunately I still have the same problem.
I have buddy press just uninstalled and reinstalled. It changes nothing. I have disabled all plugins and activated BuddyPress. The problem arises immediately. So it can have nothing to do with the other plugins.
The problems:
When I click on the navigation bar on profile, the error message 404 appears.
In the menus, no choice point for BuddyPress appears.
Please help me as soon as possible. The site should go online these days.
