Redirect all generic 404 not found to a particular page

404 pages are generated by a template in your theme, or is just a generic message created by WordPress. There is information in the Codex about creating a 404 page, but it is kinda heady. If you want to add one, you should use a child theme.

There are also a bunch of plugins that do stuff with your 404 page, so maybe something there can do what you want.

This plugin doesn’t create 404 pages, so please mark it as resolved. ^_^
