maybe_redirect_404() WordPress Function
If a user tries to access a URL on your WordPress site that doesn't exist, they will see a 404 "Not Found" error page. The maybe_redirect_404() function allows you to redirect these users to a different URL, such as your home page, instead of the default 404 page. This can be useful if you want to make sure that users don't end up on a dead-end page on your site. It can also help reduce the number of 404 errors that you see in your website's analytics.
