我在使用this tutorial时遇到了CodeIgniter似乎相当普遍的问题。我一直收到404 Page Not Found错误。
我在以下问题上尝试了各种建议的解决方案，但绝对没有运气。
CodeIgniter: 404 Page Not Found on Live Server
codeigniter not work at live page not found error on server
Codeigniter showing 404 Page Not Found on Hostgator
CodeIgniter 404 Page Not Found On Godaddy
我可以在index.php中加载默认的欢迎消息，如果我将欢迎消息复制到main.php（并更改类名），一切正常。我的控制器（Main.php）和模型（User_model.php）也遵循所需的首字母大写。
我已经对我的文件名进行了三次检查，尝试了所有建议的.htaccess文件，并在网站中没有解决方案编辑了我的config.php。
编辑：在尝试@SarangaR和@dhruv jadia的建议后，我仍然遇到同样的问题。这是错误日志
