Redirect 404 Pages to the Homepage

Sends visitors who hit a missing page to the homepage instead of showing the 404 template.

Code

add_action( 'template_redirect', function () {
    if ( is_404() ) {
        wp_safe_redirect( home_url( '/' ), 301 );
        exit;
    }
}, 99 );

Search engines treat mass redirects to the homepage as soft 404s. A helpful 404 page or specific redirects are usually better.
