Like button Error

On blastmagazine.com our Like button has worked with the same code for a long time, but last week it started giving us an error:

The app ID specified within the "fb:app_id" meta tag is 开发者_JAVA百科not allowed on this domain. You must setup the Connect Base Domains for your app to be a prefix of http://blastmagazine.com/the-issue/the-top-five-failed-apple-products/.

This is the code we've been using:

<iframe src="http://www.facebook.com/plugins/like.php?href=<?php the_permalink(); ?>&amp;layout=standard&amp;show_faces=false&amp;width=200&amp;action=like&amp;font=arial&amp;colorscheme=light&amp;height=35" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:200px; height:35px;float:right;" allowTransparency="true"></iframe>

We also have Facebook comments enabled, but that appears to be working correctly.

• App ID does not match domain
• Required Property Missing (og:image)

Correct your AppId (check if your App shows in your list) and add og:image meta tagg
