Please update 404 to 410

WP Job Manager job listings are essentially a custom post type in WordPress. Deleted job listings follows the same logic how WordPress handles deleted post, which is to remove the page directly resulting in an error 404.

As a workaround, you could look into third-party plugins such as Yoast SEO that apply a 410 header to the deleted pages. For more information: https://yoast.com/deleting-pages-from-your-site/.
