我正在使用 php 和 mysql 创建一个配置文件页面，使用 get 方法从这样的 url 获取用户名，(http://localhost/Unnamed%20Site%202/resources/username)所以我使用了 .htaccess 但问题是我放置 .htaccess 的根文件夹消失了，我得到了来自浏览器的错误消息：
内部服务器错误服务器遇到内部错误或配置错误，无法完成您的请求。请联系服务器管理员 admin@localhost 并告知他们错误发生的时间，以及您所做的任何可能导致错误的事情。服务器错误日志中可能提供有关此错误的更多信息。
任何人都可以帮助我？？
这是 appache_error.log
