I have seen that we should add header information to all pages like: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml" <?php language_attributes(); ?>>
Is this the only solution to use Facebook and XFBML Like Button & Social Plugins? <meta property="fb:admins" content="YOUR-ADMIN-ID"/> <meta property="fb:app_id" content="YOUR-APP-ID" />
