我在EC2实例上安装了干净版的Wordpress，PHP和Apache。我的文档根目录是/var/www，Wordpress在/var/www/wordpress中未加标记。如果我得到http://www.example.com/wordpress，我会得到：
$ wget https://www.example.com/wordpress/
--2018-03-10 18:05:21-- https://www.example.com/wordpress/
Resolving www.example.com (www.example.com)... IP, IP
Connecting to www.example.com
(www.example.com)|IP|:443... connected.
HTTP request sent, awaiting response... 404 Not Found
2018-03-10 18:05:22 ERROR 404: Not Found.
但是，如果我将index.php中的现有代码注释掉并放入echo('foo');，我会得到：
$ curl https://www.example.com/wordpress/
foo
所以显然它正在加载index.php很好，我猜它在Wordpress包含堆栈中找不到一些“更深”的文件？但我没有在错误中看到任何内容，也没有访问有关它的日志：

关于如何调试这个的任何想法？
