can YARPP be used to product (ecommerce themes)?

The first question is how your products are stored. Is there a custom post type for products, or are these actually posts? Did you create the code to create the custom post type yourself?

In Xenastore, the product is different with the post. I do not create the code by myself.It is coming from the themes.

So, the xenastore themes has Post and Product. The themes has product.php and single-product.php. It also has single.php for the post.

Actually to add the product is similar with to add the post, but product has price and department (in post we called it category), but product does not have tags. I do not see any custom post type in the product.

Since the file there is single-product.php, my assumption is that this is a custom post type called “support”.

You’ll need to get the yarpp_support attribute turned on for that custom post type, however it’s registered, so I suggest you contact the Xenastore folks and ask them for their help.

Sorry I can’t resolve this for you easily myself. :/
