Hello,
With the cart view I mean what visitors see when they click on "cart" in our menu.
index.php?option=com_hikashop&view=cart&layout=show
To edit that page displaying, you'll just have to edit the "Show" file of the "Cart" view of your front-end template via "Hikashop->Display->Views".
With the checkout they use this :
index.php?option=com_hikashop&view=checkout&layout=show
And for that page displaying, you'll have to edit the "show_block_cart" file of the "checkout" view of your front-end template via "Hikashop->Display->Views".
Kind regards,
Mohamed Thelji.
