Up until about 10 days ago I had a fb page that was linking to another fb page which had a like button and was showing the likes that have been voted.
Now I notice that the link from the 1st page to the 2nd one has an extra GET parameter (_fb_fromhash) that seems to be the reason why no more likes are shown. Now it displays "be the first to vote".
no other changes have been made, does anyone have a clue?
