在Wordpress中调用CodeIgniter get_instance会导致404

在过去的一天里，我一直在努力让Wordpress与Codeigniter很好地发挥作用。我有一个用Codeigniter编写的父应用程序，我试图用它来控制对Wordpress安装的访问。

到目前为止，我已经很幸运地获得了一个Codeigniter实例(通过get_instance())来显示，并进行了必要的修改，以使两个应用程序在大多数情况下互不干扰。

然而，我现在对Wordpress站点的根index.php之外的任何内容都束手无策。

URL看起来像/parent/content/external/wordpress，其中"parent"是Codeigniter的根文件夹，wordpress是wordpress的根文件夹。

我可以加载example.com/parent/content/external/wordpress(带或不带index.php)，但任何像wordpress/sample-page导致Codeigniter 404错误。

似乎Codeigniter正在尝试将URL解析为控制器和方法，但失败了。我在CI日志中得到404错误，指向Wordpress url的第一段(上面示例中的示例页面)。

有人知道我怎么可能得到CI停止试图解决时，通过代码被塞进Wordpress index.php文件加载?

该文件的内容粘贴在下面。谢谢你！
