我才意识到*empty WP_Query object* 在我的普通wordpress上安装。我重置了DB，停用了所有插件，并激活了TwentyTen作为主题，但每个请求（面向公共和管理）的完整对象都是空的。无论我是请求“Hello World”帖子还是404. 一切都是空的。这有什么原因？

Edit 1<这是我检查的方式WP_Query:

// inserted on top of the functions.php file, 
// so it\'s equal to a function hooked into the \'after_setup_theme\' hook  
// i also tried other hooks (which should make no difference) and got the same result.
    echo \'<pre>\'; 
        print_r($GLOBALS[\'wp_query\']); 
    echo \'</pre>\';
