Killer app, but I'm having trouble publishing my posts to my FB app. I do have the "Publish to FB App" and "Publish to your FB Profile" buttons active, but when I click either, I get this box: http://www.thelazycaveman.com/wp-content/uploads/2011/02/fb_post.png
And when I click through to FB, I get this lovely, non-descript error: http://www.thelazycaveman.com/wp-content/uploads/2011/02/fb_error.png
Any thoughts? The rest of the plugin seems to be working fine, so it's likely on FB's end.
My app is here: https://www.facebook.com/apps/application.php?id=139226969473478
