Как убрать shop и product-categoty из URL Woocommerce?
Вообще сильно не рекомендуют  https://docs.woocommerce.com/document/removing-pro...
Но если оооочень  хочется, то действуйте./**
	 * Для термина  - product_cat
	 */
	add_filter( 'request', 'change_requerst_vars_for_product_cat' );
	add_filter( 'term_link', 'term_link_filter', 10, 3 );

	/**
	 * Для типа постов - product
	 */
	add_filter( 'post_type_link', 'wpp_remove_slug', 10, 3 );
	add_action( 'pre_get_posts', 'wpp_change_request' );

	function change_requerst_vars_for_product_cat($vars) {

		global $wpdb;
		if ( ! empty( $vars[ 'pagename' ] ) || ! empty( $vars[ 'category_name' ] ) || ! empty( $vars[ 'name' ] ) || ! empty( $vars[ 'attachment' ] ) ) {
			$slug   = ! empty( $vars[ 'pagename' ] ) ? $vars[ 'pagename' ] : ( ! empty( $vars[ 'name' ] ) ? $vars[ 'name' ] : ( ! empty( $vars[ 'category_name' ] ) ? $vars[ 'category_name' ] : $vars[ 'attachment' ] ) );
			$exists = $wpdb->get_var( $wpdb->prepare( "SELECT t.term_id FROM $wpdb->terms t LEFT JOIN $wpdb->term_taxonomy tt ON tt.term_id = t.term_id WHERE tt.taxonomy = 'product_cat' AND t.slug = %s", array( $slug ) ) );
			if ( $exists ) {
				$old_vars = $vars;
				$vars     = array( 'product_cat' => $slug );
				if ( ! empty( $old_vars[ 'paged' ] ) || ! empty( $old_vars[ 'page' ] ) ) {
					$vars[ 'paged' ] = ! empty( $old_vars[ 'paged' ] ) ? $old_vars[ 'paged' ] : $old_vars[ 'page' ];
				}
				if ( ! empty( $old_vars[ 'orderby' ] ) ) {
					$vars[ 'orderby' ] = $old_vars[ 'orderby' ];
				}
				if ( ! empty( $old_vars[ 'order' ] ) ) {
					$vars[ 'order' ] = $old_vars[ 'order' ];
				}
			}
		}

		return $vars;

	}
	
	function term_link_filter( $url, $term, $taxonomy ) {

		$url = str_replace( "/product-category/", "/", $url );
		return $url;

	}

	function wpp_remove_slug( $post_link, $post, $name ) {

		if ( 'product' != $post->post_type || 'publish' != $post->post_status ) {
			return $post_link;
		}
		$post_link = str_replace( '/' . $post->post_type . '/', '/', $post_link );

		return $post_link;

	}

	function wpp_change_request( $query ) {

		if ( ! $query->is_main_query() || 2 != count( $query->query ) || ! isset( $query->query[ 'page' ] ) ) {
			return;
		}
		if ( ! empty( $query->query[ 'name' ] ) ) {
			$query->set( 'post_type', array( 'post', 'product', 'page' ) );
		}

	}
