Hi @shahzeenfarooq, thanks! Now that I added to the shop page and removed it from home, it works now.
Hi @frankremmy,
I am using the built-in WooCommerce layered nav widgets, I am filtering by attribute, the attribute I am using to filter is an existing attribute, not one created specifically for each product.
Status report is here: https://gist.github.com/smoeast/b121efe3c3429981b132f716f941d9e0
Thanks for your help!
