BuddyPress.org

I have just updated my BuddyPress theme and migrated my user database to the new theme. I also have a separate WordPress install of ClassiPress, which is another wordpress theme for classifieds. Before I made the buddypress theme change the user database was linked together so when a user logged into buddypress they were automatically logged into the classipress site which is only a section of the site when you click on the menu of the buddypress site.

I have asked a few developers to simply recreate the link again to have all my users linked to the classipress site but they cannot seem to do it or understand how to do it when this was working perfectly fine before the theme change.

Any advice will help and sorry for the horrible explanation as I don’t know much about websites and the language.
