Hi
The "task-cancel_order" part of the cancel button has been the same in HikaShop for 15 years.
So the problem is likely not that this URL is wrong.
When you click on that URL, HikaShop will first cancel the order and then redirect you back to the checkout.
So, I dont see a reason for a 404 at this point.
However, if you have the "clean cart when order is" setting set to "created" in the HikaShop configuration page, then the cart will already be cleared and in this case, the checkout will redirect you to the "URL where to redirect when the cart is empty" that you configured in the HikaShop configuration:
www.hikashop.com/support/documentation/5...onfig.html#main_cart
And if that URL is wrong in some way or not accessible to the user because of access rights, or language restriction or something else, he will get a 404.
So the most likely cause here is that what is entered in the "URL where to redirect when the cart is empty" setting is wrong. That's the first thing I would recommend checking.
