FlyBox Facebook tab shows no content or posts

Hi.. The plugin does not show any posts in the facebook page when hovering over the tab. the tab comes out and has the FB account name and friends pics at the bottom of the page but no posts are recorded there and I know there have been posts and feeds. This is the same on several sites that I am using the WpFlyBox … Any suggestions out there? Thanks in advance. I think I am using the latest updated version of the plugin 5.6
