Why do filters do not appear in my shop/product taxonomies page?

Hi,

Check if you are using standard WooCommerce shop page, because the plugin, explicitly conveived as an extension for wooCommerce, works only in the specific pages created by WooCommerce plugin. So, if you have created a custom page to show your products (using shortcodes, widgets, page builder etc.), the plugin cannot work because it relies on specific parameters set by WooCommerce pages and that are not specified in custom pages.
