问题 I had a simple little php code that allowed me to force users to download videos from my site rather than playing it in the browser <?php $path = $_GET['path']; header('Content-Disposition: attachment; filename=' . basename($path)); readfile($path); ?> Since I moved my site to a new server, there seems to be a permission problem where I am getting a 403 Forbidden "You don't have permission to access /download-stream.php on this server." the php file is set to the same permissions as before
