 * Hi there. I am trying to get WPBook Lite to work, but cannot get it to post to
   a facebook page. It works to the user wall, but not to the page. I am pretty 
   sure that I have all the IDs correct. This is all I get from a test post in the
   debug log:

 * I have made some changes to the settings since generating the Stored access token,
   but every time I click to generate it, I get the same one. Not sure if that is
   affecting this.

 * Scratch that. It was indeed the access token. I finally was able to regenerate
   one and it now works. And really well!

 * The “Function does not exist or no thumb” just means your either running a version
   of WordPress which does not have the get_the_post_thumbnail function, or (as 
   the error says) the post in question does not have a Post Thumbnail (aka “featured
   image”).
 * It won’t prevent WPBook from posting, but what will happen is that when you post
   Facebook will come look at the post and “choose” an image for you, since you 
   haven’t told WPBook which image it should use as the post thumbnail.
