I checked this url, and you certainly have some restrictions from server, possibly from Wordpress-managed .htaccess file and/or Wordpress-plugins. First of all, why can't it be accessed directly from the filename file_manager.php
? Why do you have to add a slash /
after? It's a file not a directory. And then, how is the script supposed to access itself if access is forbidden? Actually, this could be because you have added the file into /wp-content/uploads/
which might have some security limitations ... Why not upload it in your own dir somewhere?

You can't have a PHP application running from an area that your Wordpress is trying to block. Or if it needs to be there, you need to manage the WP .htaccess
file where WP (or some WP-plugin) is adding rules that is blocking direct access to PHP files in the wp-content/uploads
dir.
