Useful code. I noticed that sometimes the following code,

add_filter('login_errors',create_function('$a', "return null;"));

returns a Function create_function() is deprecated

So, in your case I suggest to replace the part of code above with the following

<?php
function no_wordpress_errors(){
    echo '<style type="text/css">
    .login #login_error{
        display:none;
    </style>';
  }
  add_filter( 'login_errors', 'no_wordpress_errors' );
  ?>
