After reading https://www.ads-software.com/support/topic/login-61?replies=31

New update below:

// Are they visiting wp-login.php?
$visiting = array('wp-login.php', 'wp-signup.php', 'wp-register.php', 'login');
if ( in_array($super_base, $visiting))
	$this->throw404();

//We don't break the media uploader while the user is logged in
if ( is_user_logged_in() == false ) {

$user_visiting_loggedin = array('async-upload.php', '/async-upload.php', 'wp-admin/async-upload.php');

if ( in_array($super_base, $user_visiting_loggedin))
	$this->throw404(); 

                 }

@WimCosse

the solution is here https://www.ads-software.com/support/topic/wp-loginphp-is-still-showing

Solution (based on Lockdown WP Admin Version 2.2):

go to plugins/lockdown-wp-admin/src/Lockdown

Edit Application.php

about line 149 or AFTER

$blog_url = trailingslashit( get_bloginfo('url') );

ADD

$blog_urlHost = parse_url($blog_url);

if( $blog_urlHost['host'] != $_SERVER['HTTP_HOST'] )
	$this->throw404();

IF you WANT to hide wp-signup.php and wp-register.php

about line 166 Replace

// Are they visiting wp-login.php?
if ( $super_base == 'wp-login.php')
	$this->throw404();

With

// Are they visiting wp-login.php?
$visiting = array('wp-login.php', 'wp-signup.php', 'wp-register.php');
if ( in_array($super_base, $visiting))
	$this->throw404();

Have you tried to regenerate the permalinks ?

Access your site via ftp and then delete the wp lockdown plugin

Weird. You must have used the same name for one of your pages. You should change the name and see if Google finds it again. And tick the hide option.
