Hi,
To be responsive, you need to add these following properties in the frontend default css file:
.hikashop_cart_products table, .hikashop_cart_products table thead, .hikashop_cart_products table tbody, .hikashop_cart_products table thead th, .hikashop_cart_products table tbody td, .hikashop_cart_products table thead tr, .hikashop_cart_products table tbody tr {
display: block;
}
Regarding the "Proceed to checkout" button, it has been fixed and will be present in the next release which should arrive soon.
Else you can edit the view "cart / showcart" and replace:
if($cart_type == 'cart' && $this->params->get('show_cart_proceed',1)) echo $this->cart->displayButton(JText::_('PROCEED_TO_CHECKOUT'),'checkout',$this->params,$url_checkout,'');
By:
if($cart_type == 'cart' && $this->params->get('show_cart_proceed',1)) echo $this->cart->displayButton(JText::_('PROCEED_TO_CHECKOUT'),'checkout',$this->params,$url_checkout,'window.location=\''.$url_checkout.'\';return false;');
