That sounds like a bug with JomSocial itself that they've posted a fix for. Please see the thread below:
www.jomsocial.com/blog/joomla-3-3-jomsocial-conflict

I hope that helps get you going. This is not something with JFBConnect or that we could fix at all on our end.

Thanks,
Alex

No problem. Glad to be of help, and I hope that solution helped to get you going. If there's anything else we can do for you, just let me know.

Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
