WooCommerce check: If WooCommerce is not active, the plugin deactivates itself and shows an admin notice. Install WooCommerce first, then activate this plugin.
Default preset created: A “Default” preset is seeded with category, price slider, availability, and attribute filters. It is enabled immediately, so your shop page starts filtering right away.
Settings page: Access the plugin settings at WB Plugins → Ajax Filter in the admin menu.
