I see the button 'Grant Publish Permission' on the settings page after installing the plugin under 'Fan Page Publish Permission is needed to publish stories to the Fan Page automatically' section. When I press it for the first time, it shows standard FB dialog about permissions and when I allow access and click 'save settings', I am getting back to the page with button 'Grant Publish Permission', so it seems the permissions are not granted (the button doesn't show the inactive text '... permission granted' like the two buttons above, but suggests me to grant the permissions again). When I press the button again, it shows a pop-up window which contains the main page of my site. Nothing happens and I can't actually GRANT permissions to post to my page. What am I doing wrong? Thanks.
