User group creation redirect in BP

Hey everyone,

Having some trouble with creating groups. I, as suer admin, can create groups no problem. When a user (or my user-level debug account) try to create a great it goes to step one, but then almost instantly redirects back to the root url

I'm using WP 3.1.3, and BP 1.2.8
Other plugins include:
Wiki (from WPMU Dev)
Jet Event System for BuddyPress
CubePoints Buddypress Integration
Buddypress Sitewide activity widget
BuddyPress Group Email Subscription
Buddypress Widget Pack
BuddyPress Links
Buddypress Humanity

Any help on this would be much appreciated, as you can imagine this is a serious problem :S
