Hmm, I dunno, read your post again and I would separate the issue of FB and try to figure out why the dynamic page doesn’t always display as expected. Are you sure that the data in your collection lines up properly with the relevant fields? If Preview and Live differ in their behavior that would indicate that you have different data in the sandbox (Preview) database and the Live database. You might want to check the contents of the databases. As far as the FB stuff - I’m stumped.
