Disable URL Guessing in WordPress

Placing the following PHP code snippet below in your theme’s funtions.php file will disable a WordPress feature that attempts to automatically redirect a bad url to an actual post or page with a similar url.

Please note, if there are any broken links to your website or it’s pages that benefit from this feature it will now lead to a standard 404 error page.

add_filter('redirect_canonical', 'pz_no_redirect_404');

function pz_no_redirect_404($redirect_url)
{
    if (is_404()) {
        return false;
    }
    return $redirect_url;
}

Hi Joseph,

Thank you for coming up this piece of code, but unfortunately it didn’t seem to work for me.

WP 5.7.2

Thank you
