Have an easy one (hopefully).
When a non-logged-in visitor leaves a comment and comment moderation is enabled, they are shown a "Your comment is awaiting moderation..." preview box of their comment.
The theme check for this is $comment->comment_approved returning true.
Well all of a sudden my visitors (checked it myself) are not shown this message, however I still see $comment->comment_approved is set properly in the loop.
Seems like the comments loop just suddenly stopped looking for posts that were not yet approved.
Any troubleshooting ideas?
