Hi Pleer. I've read the previous thread on this topic and have tried manually adding:
within the html tag, but with no success. Although I've tried that method, I've since removed it because I do see the Open Graph and fb ... fbml printed to the post via the plugin by selecting XFBML, Open Graph, and Namespace in the settings section. (Manually entering it created a second instance)
So the Comment box isn't shown in IE8, although it is shown in Chrome, Firefox, and Safari. I've noticed that when I click any link on the page (post), the box draws itself and appears to be contacting facebook.
I've disabled things such as caching plugins and WP-Minify to try to rule out JS problems. I just can't figure this one out.
