The module adds a special product named “Product customization”
This special product is used to add the customization cost to the cart because customizations in PrestaShop 1.6 cannot have a price impact
So the module varies the price of this product to reflect the total customization cost
This product should be enabled to have a correct cart total
Please note that in PrestaShop 1.7, this special product is no longer needed because customizations can have a price impact the same as combinations
You can rename this product to anything you want, such as “Customization cost” for example
