Hi Jerome,
Thanks, I've attached a few screenshots, maybe helps for finding the problem.
On 03.jpg and 03_withnochildproduct.jpg you can see that system count points for that product, which is a parent product (with no child products - named: KnitPro Spectra Chunky kötőtűkészlet).
I've also found a strange thing: when order is created the child product is saved this way in the #__hikashop_order_product's order_product_name: Knitpro Nova fém kötőtű 100-as damillal<span class="hikashop_product_variant_subname">: 2,25</span>
Is that normal? Because some user's complains, that they are unable to put child products into cart, but I'm unable to reproduce it, on any devices I tested...
Regards,
