wordpress出现以下错误：

Notice: Trying to get property 'queue' of non-object inE:\phpstudy_pro\WWW\wp-includes\script-loader.php on line 2781

Warning: Invalid argument supplied for foreach() in E:\phpstudy_pro\WWW\wp-includes\script-loader.php on line 2781

$wp_styles没有设置全局，因为您正在删除初始化它的代码。

解决办法：

function.php添加以下代码

add_action( 'wp_head', 'wp_styles', 1 );
