@peternicholls – It looks like you created sub-blogs “members” “blogs” and “groups” which you shouldn’t have done. Delete those sub-blogs. Let BuddyPress automattically generate those pages when you click on the links. Just tested the theme and it’s working great on 1.2-rare bp-sn-parent.
If that’s not the case, it would help us help you if you answer these questions – https://buddypress.org/forums/topic/when-asking-for-support
