That setting changes the behavior of the add to cart to what you describe if turned on. So make sure that it's turned off, as it should be by default, and it will work like you want.

With the latest version it went from a 'ADD to cart' to a 'CHANGE the cart QTY' concept. Can you please have a validation from your side.

It must come from the line: Code: <input type="hidden" name="add" value="<?php !$this->config->get('synchronized_add_to_cart', 1); ?>"/> which should be: Code: <input type="hidden" name="add" value="<?php !$this->config->get('synchronized_add_to_cart', 0); ?>"/> in the file components/com_hikashop/views/product/tmpl/add_to_cart_listing.php Because of that, as long as you don't save once the configuration page with that setting "Synchronized add to cart" turned off, this piece of the code will think that the setting is activated and thus the add to cart on listings will try to replace the quantity of the product in the cart instead of adding to it. So you have three solutions: - save the HikaShop configuration once - change that line of code - download HikaShop's latest version install package on our website and install it on yours to get the patch.

I already had done a configuration save. 2. I could not find the code in add_to_cart_listing.php, I did find it in add_to_cart_ajax.php After changing the code as instructed, the issue still remains. 3. I can not install the patch for the moment. Need to wait for the weekend. Anyway, not sure if it will bring a fix based on the above.
