Wordpress writes the title of the page by first letters and opens it, how to fix it?

Question

WordPress

Good afternoon. Such a situation, let's say there is a page " http://sayt.ru/sample-page/ ", and when I type " http://sayt.ru/sa" wordpress instead of returning a 404 error opens a page at " http://sayt.ru/sample-page/ ", tell me if anyone knows how to fix this?

Answer 1

This is an automatic redirect in WP.
You need to add the following code to your functions.php file to disable this feature:

function remove_redirect_guess_404_permalink( $redirect_url ) {
    if ( is_404() )
        return false;
    return $redirect_url;
}

add_filter( 'redirect_canonical', 'remove_redirect_guess_404_permalink' );

Answer 2
