[Plugin: SEO Facebook Comment] Plugin doesn't detect me as moderator/admin

After installing the plugin, I was automatically detected as moderator/administrator. The next morning, it was gone! I can’t moderate comments any more and when I’m on a post, the comments box shows me as just another commenter. What do I do? Already tried changing/updating secret ID and all that..
