Hi,
I just tried on my end and removing that part, correctly display the wishlists interface. So you have maybe edited the view in the wrong template.
But, there is no wishlists displayed because, the current user don't have anyone, that's the way the system is working.
If you really want to display all the wishlists to anybody, so this is not a common way of using wishlists and this is not handle by HikaShop. So you will have to edit core file in order to have what you want.
To show all the wishlists to everybody even if he is not registered you have to edit the file "components/com_hikashop/views/cart/view.html.php", function "showcarts()". It require PHP knowledges.
