I am using Facebook comments on couple of my blogs at the moment and I just found that somehow magically all the previous comments made on posts are gone and are no longer being displayed. I'm using wordpress for all of these blogs and Facebook Comments for WordPress to manage all the facebook comments. But somehow they all disappeared all of a sudden. Another problem which I've been facing lately is that I can't seem to moderate the faceboook comments. When I go to http://developers.facebook.com/tools/comments where there should be a list of all the comments made on my sites (against the Applications that I've created just for the sake of comments), there is nothing there. This has been the thing from the starting, before the comments vanished on my site, today So technically, there are two issues to solve here.
