title: "OAuthException","message":"Error validating application."
body: <p>up until 4 days ago this was working just fine, now I keep receiving an error when trying to post a youtube video on my friends (or even my own) wall.</p>
  
  <p>Reading user ids from list.txt and send them a video
  Posting video to user id: me
  {"error":{"type":"OAuthException","message":"Error validating application."}}</p>
  
  <p>I am getting the same error with an application which i created on a friends facebook account when trying to do the same thing.</p>
  
  <p>Does anyone have an idea why this is and what I can do to fix it?</p>
  
  <p>Thank you!</p>
