Buddypress Groups Duplicating the posts

Hi All

Im having some trouble with one of my BuddyPress enabled websites. Every time a user posts to a group, the posts is duplicated. It only seems to be doing this on the live site though. It works perfectly on our demo sites. ( Live and Demo sites run the same code )

I deactivated all of the plugins except Buddypress but the error still seems to happen.


here is a list of the plugins and software currently used.
Wordpress 3.0.4
Buddypress 1.2.7
BuddyPress Group Email Subscription 2.7.9
BuddyPress Template Pack 1.0.2
WordPress Hashcash 4.5.1
BP Group Documents 0.3.5
