Changing your link structure in WordPress can lead to all of your old links breaking and returning a “404”. But no more! If someone goes to an old link for your site, I’ll find the new link and redirect them there automatically.
No configuration. No one-by-one setting of the new link structures. No wrestling with complicated regex patterns. Just install me and relax.
Redirect 404s works with posts, pages, and custom post types (like ecommerce products).

Redirect Old Links

Did you change your permalink structure and now have old links "404ing"? I'll redirect those old links to their new one for you.
