I put a like button on this page, http://wikidia.wikispaces.com/ and got likes. I then made a facebook page, Wikidia, http://www.facebook.com/pages/Wikidia/144267418967163

Now my original likes have disappeared, and the button on the original webpage has ceased to work. It shows no likes. If you click it, it will show one like, and quickly resets itself.
The facebook entry, 'Wikidia - home' still shows muliple likes when you search for it in facebook.

What's going on?

Here's the code in the like button.

<iframe src="http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fwikidia.wikispaces.com%2F&amp;layout=button_count&amp;show_faces=false&amp;width=450&amp;
action=like&amp;colorscheme=light&amp;height=21" scrolling="no" frameborder="0" style="border:none;
overflow:hidden; width:450px; height:21px;" allowtransparency="true"></iframe>
