Buddypress register link doesn' work

Hi,

I am using the latest buddypress version with wordpress but a different theme (from rockettheme.com).

The “register” link on the frontpage is not linked to the “register” page. I can fix that in the admin dashboard by going to settings–>buddypress–>pages.

Here I need to create a site called “register” first.

My problem now is that this site is indeed called “register” but has no registration function whatsoever.

Can someone help me?

Thanks a lot for your support,
Fabian
