The function is in the file:
/includes/classes/payment.php

Check your server for this file what is the ID on it?

* @version $Id: payment.php 5382 2006-12-24 18:22:47Z drbyte $

Check on your server for the files:
/includes/pages/checkout_payment/header_php.php

* @version $Id: header_php.php 6100 2007-04-01 10:24:05Z wilt $

If they are correct, delete and reload the files ...
