I have a similar problem.

The friend request is successful. But the friend accept and reject is unsuccessful.

The accept and reject will both have diff wpnonce values. For example,

accept button goes,

http://antblogz.com/members/admin/friends/requests/accept/3?_wpnonce=8db229ebf2

remove button goes,

http://antblogz.com/members/admin/friends/requests/reject/3?_wpnonce=e838b60f25

And both accept and reject prompts this on the page.

Are you sure you want to do this?

Please try again.

But when the user clicks “Please try again” link, it does nothing and returns to the “Friendship Request” page with the request unconfirmed.

WPMU 2.8.4a with Buddypress 1.1.2.

I am having the same problem as well…There are also many themes that I installed that links to wp-signup.php for registration of new accounts but now it is just a blank page instead of redirecting to the new buddypress registration page…
