So, thanks for the demo. We are now getting a 500 error from your server.
Can you please add the following lines to the very top of your PHP script:
ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(-1);
Also please create a separate file in your scripts folder like so:
<?php
phpinfo();
?>
Name this file info.php
Please let me know when you have done this.
