I have WooCommerce 3.4.4 and Search & Filter Pro 2.4.4 installed on my WordPress 4.9.8 installation. I have the WooCommerce products (shop) page displayed on an interior page /product/. When I set the Search Filter -> Display Results -> to “WooCommerce Shop” the /product/ page returns an Error 404 page. The individual product pages work fine, it’s just the shop page that returns this error. I followed the instructions per this url, https://searchandfilter.com/documentation/3rd-party/woocommerce/, but the error persists. When I set the Display Results to anything else, the shop page returns. I’m using a custom theme. What’s curious is, when I use a WordPress theme like “twentyseventeen” or even a WooCommerce theme like “storefront” the shop page returns. Though, I tested several different custom themes that were hosted at WordPress.org, that’s not built by WordPress, and the shop page disappears again. What is this plugin looking for that WordPress themes have, that custom themes don’t seem to have? I thought I solved this before by using the old WooCommerce method of creating the WooCommerce.php and adding theme support, but with recent changes it looks like we need to use the latest WooCommerce method, and solve why Search Filter Pro breaks the shop page. – Thank you!
