Looks like everything is plumbed correctly - I get the green light on the plugin interface in WP. I make a post (tried both with and without a photo in the post) and I get message that the post has been "Posted to Facebook" and I can see the "yes" in the column when looking at all posts - yet - on FB the post never shows up.
I look in the developers console on FB and see that I have published 3 stories (which I assume translates to posts) yet .... I dont see them.
Any help would be appreciated - we have literally wasted days with other plugins and just today purchased your thinking it would solve the problem.
