[Plugin: BuddyPress] Broken link. Error 404

There is a lot of issue with this version.

Delete user or mark as spammer link leads to “error 404”.
User email confirmation stopped working.
The plugin Buddypress moderation stopped working.

Note: I have kept the buddypress toolbar.

And sorry for my bad english, my native language is french.
