I've read many other people are having this same problem yet I haven't found a fix that works for me.
I have 'Use Facebook for comments' ticked and 'Override WordPress discussion settings' also ticked. In this state I get no comments box showing what so ever.
If i untick 'Override WordPress discussion settings' then both comment box show.
I would like ONLY for the Facebook comment box to show.
Here is a link to the WP post where you can see no comments at the end.
