Hi,
I don't ; but I got a "login" page instead.
In the product page, the link "/atoa-mobile-accessories-cad/product/updatecart" is not blocked by Joomla ACL.
In the home page, the link "/product/updatecart" is blocked.
HikaShop does not (and never did) check Joomla tokens for the "add to cart".
You should assign a valid menu to your product listing module in the homepage in order to not point to something else than HikaShop and generate unwanted side effects.

By the way, do not send me private message, use the "contact us" form instead.
