Use a 404 page not found instead of redirecting

[henry.wright]

I have my permalinks set to post ID so I can access my posts like:

• example.com/625/
• example.com/76/

The title of one of my posts is "Post of the year award". I can access this particular post like:

• example.com/118/

The problem:

If a user types the URL example.com/post/, they seem to be redirected to "Post of the year award" example.com/118/.

Likewise, if a user types URL example.com/baseball/, they seem to be redirected to "Baseball is for everyone" example.com/128/.

As you can see this behaviour is not really helpful in my case. The user ends up viewing a post they might not necessarily want to be viewing.

I propose that 404 Not found pages be used instead of the redirects.

Duplicate of #16557. Try a workaround from there:

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' );
