I have checked and I dont have anything like that, except the custom .htaccess, which I have tried stripping down and made no difference.
Is this a clue, this problem does not happen when you add products to the cart from within a category, it only seems to happen when you try and add a product from the online shop landing page?
So...
scubazone.bulletdesign.com/online-shop
, select a product and add to cart = problem.
scubazone.bulletdesign.com/online-shop/c...s/51-fin-accessories
, select and add product from with category page and its ok ??
Any help ??
Thanks
