   If you receive a Fatal error: Call to undefined function has_post_thumbnail() warning, add the following to your theme's functions.php file:

   add_theme_support( 'post-thumbnails' );

   For an Open Graph implementation, use this plugin instead:
   http://wordpress.org/extend/plugins/like

   It has complete support for the Open Graph protocol, and you can (optionally) display Facebook's new Like button on your posts.
