I love this plugin because it's so simple to integrate into a page and it works quite well so far. But all that doesn't help, if I can't moderate it.
The suggestion, from the other thread, of re-entering the app-id didn't work. I tried at least 8 other plugins, but this one works the most for my situation.
I added the the <meta-tag> with the user-ids into the <head> but it won't show the moderation options. Like this tool http://developers.facebook.com/tools/comments won't show any comments.
Hopefully somebody can help me with this issue.
Help is highly appreciated.
