我是codeigniter的新手，我从过去几天开始开发了一个网站。该网站在 localhost 上运行良好。但是当我在实时 Web 服务器上测试该网站时，我给出了以下错误：
500内部服务器错误。您要查找的资源有问题，无法显示。我尝试了很多不同的教程中可用的 .htaccess 解决方案，但没有成功。然后我尝试了自我调试，发现当我注释掉模型加载行时，我的索引页面被加载而没有必须从数据库中获取的数据。但是一旦我从该行中删除注释，它就会再次给我同样的错误. 然后我检查了我的模型我不会发现任何这样的问题。现在我没有使用任何.htaccess。服务器上的 PHP 版本：5.2.17 codeigniter 版本：CodeIgniter_2.1.4
