将我的WordPress更新到4.4时，我遇到了以下错误：

致命错误：找不到类“WP\\u Rewrite”

出现错误的页面是我的自定义ajax，代码如下：

<?php
// Constantes propias para ajax
define("SHORTINIT",true);
define(\'WP_USE_THEMES\', false);
define(\'WP_ALLOW_MULTISITE\', false);
if (!defined("AUTH_COOKIE")){
    define("AUTH_COOKIE",false);
}
if (!defined("LOGGED_IN_COOKIE")){
    define("LOGGED_IN_COOKIE",false);
}
require_once ("../../../../wp-load.php");
//Loading code from wp-settings after SHORTINIT    
require( ABSPATH . WPINC . \'/l10n.php\' );
require( ABSPATH . WPINC . \'/formatting.php\' );
require( ABSPATH . WPINC . \'/capabilities.php\' );
require( ABSPATH . WPINC . \'/query.php\' );
require( ABSPATH . WPINC . \'/user.php\' );
require( ABSPATH . WPINC . \'/meta.php\' );
require( ABSPATH . WPINC . \'/general-template.php\' );
require( ABSPATH . WPINC . \'/link-template.php\' );
require( ABSPATH . WPINC . \'/post.php\' );
require( ABSPATH . WPINC . \'/comment.php\' );
require( ABSPATH . WPINC . \'/rewrite.php\' );
require( ABSPATH . WPINC . \'/script-loader.php\' );
require( ABSPATH . WPINC . \'/taxonomy.php\' );
require( ABSPATH . WPINC . \'/theme.php\' );
require( ABSPATH . WPINC . \'/class-wp-walker.php\' );
require( ABSPATH . WPINC . \'/post-template.php\' );
require( ABSPATH . WPINC . \'/post-thumbnail-template.php\' );
require( ABSPATH . WPINC . \'/shortcodes.php\' );
require( ABSPATH . WPINC . \'/media.php\' );

create_initial_taxonomies();
create_initial_post_types();

require( ABSPATH . WPINC . \'/pluggable.php\' );

wp_set_internal_encoding();
wp_functionality_constants( );

$GLOBALS[\'wp_the_query\'] = new WP_Query();
$GLOBALS[\'wp_query\'] = $GLOBALS[\'wp_the_query\'];
$GLOBALS[\'wp_rewrite\'] = new WP_Rewrite();
$GLOBALS[\'wp\'] = new WP();
$GLOBALS[\'wp\']->init();
wp();

if (!defined("WP_CONTENT_URL")){
    define("WP_CONTENT_URL",get_option(\'siteurl\').\'/wp-content\');
}
require_once (\'ajax-funciones.php\');
// There I have some acctions

die();
?>

在更新Wordpress之前，我发现WP\\u Rewrite（）有一个错误。该类正在文件重写中。php，如果你在法典中寻找，这是包括。

有什么问题吗？
