Hi,
I'm working with your gk_quark template and everything works fine in the checkout procedure except with the coupons.
When a coupon is activated, the checkout procedure work normally until the payment. AFTER the payment, when returning again to the template, an Error 500 occurs.
I activated the developer mode and this is the error message I get :
"Fatal error: Class 'CouponHelper' not found in /var/www/vhosts/desarrollo1.buyto.es/httpdocs/components/com_virtuemart/helpers/cart.php on line 1300"
If the line 1300 is commented, the error 500 doesn't show and the procedure apparently end fine but the "Gift coupons" dissapears from the lists of Coupons in the back-end.
Any suggestion?
Thanks!
