    Halo all, i need your help urgent, because one of my new blog has fatal error like this :

    Fatal error: Cannot redeclare is_plugin_page() (previously declared in /home/username/public_html/mydomain.com/wp-includes/query.php:461) in /home/username/public_html/mydomain.com/wp-includes/deprecated.php on line 2585

    this is the deprecated.php line 2585 :

    function is_plugin_page() {
    _deprecated_function( __FUNCTION__, '3.1' );

    global $plugin_page;

    if ( isset($plugin_page) )
    return true;

    return false;

    How i can fix it?
    1. This is a new blog, so i installed many plugins like usual
    2. i change query.php, after changing query.php, its still working well.
    3. i change the rewrite.php. after changing this i got those error.
