Hi,
We do not require the Joomla debug information, we need to see if there is an error in the page.
But for what I analyzed using your screenshot make me feel that there is not error, it is "just" that the product does not have any variant value.
Your front-end screenshot just propose "yes" and "no", it does not propose the different variants.
It means that HikaShop does not list the variants of the product, it propose the main product or no product.
Otherwise you will have the list of variants, like in the demo page (all options except the webcam) :
demo.hikashop.com/index.php?option=com_h...ow&Itemid=91&lang=en
So you will have to create the variants in the screen "manage variants".
Otherwise you can delete the characteristic, save the product and recreate it. HikaShop should create the different possibilities of variants itself.
