All BuddyPress Links Redirect to Home, not work

I have tried everything to no avail. I no it is not a WPMUDEV problem, must be some configuration o problem with BuddyPress. Pls check it out at http://www.linkedbees.com it must be something simple. Many people have this problem, but I don´t find a solution. Can you help me urgently? I would be very greatful!!

Cheers, Donald.
