.htaccess 抛出 500 错误
我正在使用 CodeIgniter，需要去掉 URL 中的“index.php”。我从 CI 教程中复制了 .htaccess 文件，清空了 $config['index_page'] = ''; 并将 .htaccess 放在根目录中。
- 如果没有 .htaccess 文件，它可以正常工作，但很难看：www.example.com/index.php/site/home
- 由于某种原因，它无法正常工作，只会引发 500 的错误。
- 在日志中有一行在每次尝试中都会重复：[Thu Dec 20 04:01:13 2012] [alert] [client 2.55.118.161] /home/morro1980/data/www/knight-guard.org/。 htaccess: 指令需要额外的参数。
- mod_rewrite 已安装并正在运行
错误在哪里，我该如何解决？
先感谢您
我的 .htaccess 文件：
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#Removes access to the system folders by users.
#Additionly this will allow you to create a System.php controller,
#previously this would not have not been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php/$1 [L]
#Checks to see if the user is attempting to access a valid file,

RewriteRule ^(.*)$ index.php?/$1 [L]
<IfModule>
<IfModule !mod_rewrite.c>

我的站点控制器：

$data['result'] = $this->math($data);
