I installed the MVS Contribution. Now, on shoping cart I get the following error Fatal error: Cannot redeclare vendor_shipping() (previously declared in /home/ianditb/public_html/revup/includes/classes/shopping_cart.php:420) in /home/ianditb/public_html/revup/includes/classes/shopping_cart.php on line 418 The function is not declared elsewhere, but any $this-> variable generates the error.
