title: facebook app is misconfigured for mobile access
body: <p>Got this error when trying to use a my Facebook app on an iPad with Safari.</p>
  
  <p>"mobile version of app is unavailble because it is misconfigured for mobile access"</p>
  
  <p>The app works fine when used in a Safari browser on a desktop. Anyone a suggestion for a solution? </p>
  
  <p>Only see this option in the settings of the app "Mobile Web URL"  which has the same value as my "site URL".</p>
