Streams App access denied 4.5

Hi,
when trying to access Streams via the Gui within Apps I now get "access denied". I have checked permissions on the directory /var/www/fusionpbx/app/streams and streams.php file and all are correct.

I have noticed that the streams.php uses:
//includes
require_once "root.php";
require_once "resources/require.php";
require_once "resources/check_auth.php";

the directory /streams/resources/ is empty


where is stream_view being called from, modules?
//check permissions
if (permission_exists('stream_view')) {
//access granted
}
else {
echo "access denied";
exit;
}

thanks,
Jim
