title: Graph API error #200 even with correct permissions
body: <p>I'm setting up a bot to auto-post on a facebook page. But when i run the script, the graph API throws the following error:</p>
  
  <blockquote>
    <p>Graph returned an error: (#200) Requires either publish_to_groups permission and app being installed in the group, or manage_pages and publish_pages as an admin with sufficient administrative permission</p>
  </blockquote>
  
  <p>but in the app's permissions, both <code>manage_pages</code> and <code>publish_pages</code> are marked as allowed, as well as the user (who is also the owner of the page) is setup as app admin.</p>
  
  <p>i know this is (or, at least, <em>was</em>) a know issue but i've found no answer whatsoever.</p>
  
  <p>is there any way to solve/work arround it?</p>
