 * Hi we installed WPbook lite and we believe we got it all set up but when we try
   to select to post to Facebook we get this message below and then if we click 
   BACK and post again, the post does post to our website, but not to Facebook –
   any ideas of what could be wrong? Thanks – site is [http://www.olafoods.com](http://www.olafoods.com)

 * Hmm. That’s a new one to me.
 * Do you have an AppID defined in your WPBook Lite settings?
 * Sounds to me like there is something gone wrong with both of those pieces of 
   information
 * Were you previously able to generate an access token successfully?

 * Hi thanks for responding! Yes we have our appid all set and we have a stored 
   token all set no problems there!! The only weird thing is that under “publish
   new posts to this page” we enter the id and save and then the id we enter disappears
   so it is always empty. It won’t save…..

 * The errors are coming from the Facebook client library itself, but seem to suggest
   an error with your settings somewhere.
 * Look at /wp-admin/options-general.php?page=wpbook-lite.php
 * on your wordpress site – the settings page for WPBook Lite.
 * What is your appID set to, and what is your personal FB profile set to?
