Filter By Attribute block

Hi @bloke,

Thanks for getting in touch.

In the second screenshot, I can see you’re using a legacy widget. More information is on this page – https://woocommerce.com/document/woocommerce-product-search/widgets/#section-2.

Can you confirm if both websites have the same versions of WordPress and WooCommerce?

Also it only works on one site

This is an indication that you might be experiencing a conflict with the theme or with another plugin. As a first step, you will want to do a conflict test following this guide – https://docs.woocommerce.com/document/how-to-test-for-conflicts/

Let us know how it goes.
