 * When I try to publish a new post, I see:
    Fatal error: Call to undefined function
   get_the_post_thumbnail() in /home/leedh/lee.org/blog/wp-content/plugins/wpbook/
   includes/publish_to_facebook.php on line 72
 * I’ll try to find the cause later today.

 * [@gadlen](https://wordpress.org/support/users/gadlen/) – update to 2.1.1 or add
   the following to your theme’s functions.php:
    `add_theme_support( 'post-thumbnails');`

 * Hmm, why is 2.1.1 not showing up as the default version to upgrade to at [http://wordpress.org/extend/plugins/wpbook/](http://wordpress.org/extend/plugins/wpbook/)?
   I’ll try your suggestions later tonight. Thanks.

 * [@gadlen](https://wordpress.org/support/users/gadlen/), You should now be able
   to automatically upgrade to 2.1.1 🙂
