Appears some core edits were made to your CB installation. The jQuery and CSS are both failing on profile view indicating some sort of conflict. I've checked plugins Joomla and CB and does not appear to be one of those. Please re-install CB 1.2.3 and latest FBC release (1.1) to remove any modifications. I can not check your FBC release because you did not check-in once you left the plugins edit page inappropriately (nor can I check-in as you made me a Admin and not SAdmin).
