Redirected to an unexpected page after member registration

I have a multisite network, buddypress, members plugin installed. all other plugins have been disabled. The buddypress registration and activate pages are set to none.

After someone registers the get redirected to a page with the following message:

"You currently have a subscription for the FOP Member subscription. If you wish to sign up a different subscription then you can do below."

The thing is they never existed on the site. Your help is appreciated.
