facebook likes

It seems that facebook likes don't like anylonger. If I bring up an image and click on like it used to post to my Facebook wall (allbeit as a privet post), yet now it does nothing at all. Is this issue limited to me or is this known?

Not sure if this is an Xenforo thing or facebook permissions,but if you like an image and don't comment it won't appear on Facebook. More so if you make a comment whilst liking the picture on xenforo the image appears on your facebook wall as private only me can view... Any thoughts on this please.
