title: Can anyone tell me what 'fb:admins' could not be parsed as type 'fbid' means?
body: <p>I am doing my best to set up open graph on my website.</p>
  
  <p>It's all working ok and looking good on Facebook, but I'm getting this error message on my site:</p>
  
  <blockquote>
    <p>Object at URL '<a href="http://www.thesocialnetworkingacademy.com" rel="nofollow noreferrer">http://www.thesocialnetworkingacademy.com</a>' of type
    'website' is invalid because the given value '159229554128788' for
    property 'fb:admins' could not be parsed as type 'fbid'.</p>
  </blockquote>
  
  <p>Can anyone tell me in fairly basic terms what I need to do to fix that?</p>
