jQuery AJAX response error (FF and Safari not working) - php

Question

In Safari and Firefox, the response part of the code is not working (i.e. from PHP-->Ajax-->jQuery). The variables definitely make it to the PHP fine (tested using mail() ), so it's probably some small error on my behalf!
jQuery:
$.ajax({
type: "POST",
dataType: "json",
data: postData,
url: "http://www.kudiclub.com/test/login/?loginsub",
success: function(data){
if(data.success==false){
$("#login .error").html(data.reply).show();
$("#login-email").val(data.email);
$("#password").val("");
}else{
window.location = data.ref;
}
}
});
PHP:
$data = array('success' => false, 'reply' => 'Username and password did not match.', 'email' => $email);
print json_encode($data);
return;
Hoping somebody can help. Thanks, Nick.
SOLUTION
After much fiddling about, it turns out that it doesn't see a full URL as a relative path. Changing the url to '/test/login/?loginsub' did the trick.

The server says: Content-Type: text/html. Is not a json document (application/json).
