can tell me wrong. thankfull.

to post page "as page", need authorize user "publish_pages" , need use page token. try add publish_pages permission list:

$config['facebook']['permissions'] = array(   'email',   'user_location',   'user_birthday',   'publish_actions',   'publish_pages',   'manage_pages',   'public_profile', );
