I cannot seem to fix this problem. I get the following after pressing the continue button on checkout_payment.php: Fatal error: Cannot redeclare class order_total in /home/acb/htdocs/catalog/includes/classes/order_total.php on line 13 I did a grep -ir "class order_total" and only see one instance of it declared. I did install the creditclass system, but have tried it with and without it activated and get the same error.. Any Ideas?
