Hi,
There are several ways to remove the add to cart buttons:
- First, you have the "catalogue mode" setting, under the "Features" tab of the HikaShop configuration page. Check that this option is turned off.
- Second, if the product has a stock of 0, the add to cart button won't appear either. So check the "quantity" setting of your products.
- Third, if the price of the product is 0, and the "display add to cart button for free products" setting of the HikaShop configuration is turned off, the add to cart button won't appear.
- Fourth, if the "available from/to" settings of the product are set such as the start date is in the future, or the end date is in the past, the add to cart button won't appear.
If it would be 2 or 4, a message should appear on the product page, and if it would be 3, the price should not appear on the product page. I checked the product page of a product on your website, and I think it's probably the first reason. So please check that setting.
