I have the same issue – it’s jquery conflict probably…
When I was opening site of my page with fancy gallery photos Be-It Facebook SideTab was lending on bottom of the page as normal div.
My premium theme which I spent a lot of money has been written by some Mamontov person – who just vanish some time ago from web.
He inside his theme put his jquery libs and my side with couple of plugins wasn’t working – especially with fancy gallery and Be-It Facebook SideTab.
Now Im moving my WP side to official WP theme – without premium shits and without problems…
Best regards,
JP
