Dirthog,
Very glad to hear it's working for you. Hopefully, all the cache will clear up soon and everything will be running smoothly for you going forward.
Kwindo,
Glad you got your issue solved. As for hiding comments, when you do that, you aren't completely deleting the comment. It will be hidden for you and all your visitors on your site. However, since comments are posted to a user's wall, when you hide it on your site, it will still be on their wall. So, as an admin, you can decide what's shown on your site, but don't have control over what others say and show up on their own walls.
Hope that makes sense, and explains why Facebook doesn't call it delete.. essentially, it is deleted from your site though.
