This was the complete code of the page (this is the POST version not the REQUEST version): <?php $response = print_r($_POST, true); echo $response; ?> Returns an empty array no matter what POST vars are sent. We fixed it by changing it to this, which I've never even heard of, but so far is working perfectly: <?php $response = file_get_contents('php://input'); echo $response; ?> I have no idea what the problem was.
