I'm just purchased JFB and I'm using it with JomSocial. The problem that I'm having is that after the invite is being sent that it's not giving the correct URL. It's giving "index.php/community/activity/register" instead of "index.php/community/register". Prior to installing JFB it was working fine with just Jomsocial.
Any help in a timely manner would be fantastic otherwise I'll have to remove JFB so I can resume invites.
So you're saying that the invite that is sent to the user (when they click the notification on Facebook.com) is the wrong URL? That URL is fully configured in the JFBCInvite module in the Invitee Welcome URL. Check that setting, and make sure it goes to the desired location.
If that setting is set for the right URL, but goes to the wrong place, definitely let us know as that's obviously incorrect.
If there's something else we're missing here, just let us know!
