simple-facebook-connect comment integration with colorlabs theme

Just wondering if someone could have a quick look at my site to let me know why they think the comment feature is not working for Facebook, twitter or google plus – http://www.progressivetalks.com (click on any post)

I am having lots of problems trying to get a nice comment thread there… Any suggestions as to a good comments.php template/theme file?
