Can not create a new Adress

[Rezureax]

Hello this is my code

require_once('templates/easybitcoin.php');
$bitcoin = new Bitcoin('user','pw','localhost','8332');

$adress = $bitcoin->getnewaddress("myname");

But the $adress is null.
It wont create the adress but why?
And how can i create a adress and store it into a string?
