That space in the middle is where our code should go.. but it's missing! JFBConnect is also adding the fb-root div, so our plugin is working, but then something's coming along and removing that extra stuff. Not good. What are you using to switch to the mobile template? Is there any settings you can disable in there to preven it from optimizing or doing whatever it's doing?
