I already checked "Use Facebook for comments"

hi again. I can't seem to reply to my last support request, so I'm starting a new ticket. (Is it possible that there is a bug with the support forum? I don;t see a reply button, and any buttons that are on the page don't seem to do anything)

Anyway, you said I should check "Use Facebook for comments" to get Facebook commenting to appear on our InvisibleOranges.com Wordpress site, but I did check that box already.

Just to be clear, I want to be able to have Facebook login and commenting on InvisibleOranges.com, and not just from Facebook.com
