I'm sorry for the delay in response. If you look at the form now, the follow button should be loading properly.
I tried quite a few things but here are the changes that seemed to fix the issue:
1. I changed the SCFacebookFollow easy-tag to the html for the fb-follow instead. I think there's a timing issue on when things are rendered and the AJAX call that was not parsing this correctly. Even changing the system plugin order did not resolve it.
2. I added code to force the parsing of the FB plugin. Because the message is being inserted by AJAX, you have to call the Javascript functions to refresh the follow widget.
<script type="text/javascript">FB.XFBML.parse();</script>
You can see the Display message in the backend form to see the full changes.
Again, sorry for the delay and hope this gets you going again.
