After deleting product properties (color, clothing size, shoe size) in trade offers, the products are not added to the cart?

Question

PHP

I am new to Bitrix. Please explain where to fix it. I installed 1C-Bitrix - Modern online store. Since I did not need the property: color, clothing size, shoe size, I deactivated them. But after that, the goods are not added to the cart and you can not change the quantity, in general, they became inactive? As far as I understand they are related to the properties ...

Answer 1

No one is friends with Bitrix?

Answer 2

Make simple products instead of sales offers.
