Hi,
d.) Go to your primary product page, select a quantity of 2 or more and ad it to the cart. The product and the option should go to the cart and this error message should appear "Limit reached. Quantity reduced for product:" (that's the option) There should be 2 or more primary products in the cart and only 1 of the option.
When I do that, I get the error "Limit reached. Quantity reduced for product: Porsche Carrera 4964" and I don't get any product in the cart. Which is what you'd expect. The main product shouldn't be added to the cart if some of the options restrictions don't allow it to be added.
For example, if you purchase 2 of this product
demo.hikashop.com/index.php/en/hikashop/...ct-page/with-options
and that there is a restriction on an option of the product, you don't want to add the product to the cart without the options. A laptop without a processor wouldn't make sense.
So as far as I can see with your example, HikaShop 3.0.1, regardless of the edition, Essential or Business, works as it should.
Which means that what you're talking about is not a bug.
If you were able to add a product to the cart while the options were not added with previous versions of HikaShop, then the bug was in the previous version, not in the new one.
e.) hopefully removing the right code (per your prior suggestion) will still defeat the "Limit reached" message, just as it does in Essential
I'm sorry but we provide support for thousands of customers and I don't remember what suggestion I gave you.
