title: Can't access Facebook Graph: OAuthException 190:467
body: <p>I can't access any of the /me/ URLs on Facebook. I tried the API doc page that generates temp links for testing ( <a href="http://developers.facebook.com/docs/reference/api/" rel="nofollow">http://developers.facebook.com/docs/reference/api/</a> ) but still get the error.</p>
  
  <p>I've also tried the API explorer ( <a href="https://developers.facebook.com/tools/explorer" rel="nofollow">https://developers.facebook.com/tools/explorer</a> ) and generated an access token with ALL the scopes (with numerous apps), yet it still persists. </p>
  
  <p>Been trying to figure this for a week now (thought it was maybe a bug?).
  Any advice? I'm just hopping it's something simple I've missed.</p>
  
  <p>Oh, and the exact error code;</p>
  
  <pre><code>{
     "error": {
        "message": "Error validating access token: This may be because the user logged out or may be due to a system error.",
        "type": "OAuthException",
        "code": 190,
        "error_subcode": 467
     }
  }
  </code></pre>
