php – Codeigniter没有输入文件指定错误

我的.htaccess在www.siteb.com/rexona内：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /rexona

#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,#previously this would not have been possible.
#‘system’ can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$/index.php/$1 [L]

#Checks to see if the user is attempting to access a valid file,#such as an image or css document,if this isn’t true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
#This last condition enables access to the images and css folders,and the robots.txt file
#Submitted by Michael Radlmaier (mradlmaier)
RewriteCond $1 !^(index.php|images|robots.txt|css)
RewriteRule ^(.*)$index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>

ErrorDocument 404 /index.php
</IfModule>

在config.php中：

$config['index_page'] = '';
$config['base_url'] = '';
$config['uri_protocol'] = 'AUTO';

每当我尝试访问控制器时,我都没有指定输入文件.但它确实加载了默认控制器,但我也无法访问默认控制器中的任何方法.

有什么想法吗？
谢谢.
