我刚刚完全按照安装指南在我的 Linux 系统上安装了 Flexi Auth 插件
当我导航到代码时http://localhost/codeigniter/，它正在显示精美的演示页面。但是，当我从顶部菜单单击“演示”链接时，找不到显示页面错误
Not Found
The requested URL /auth_lite/demo was not found on this server.
Apache/2.2.22 (Ubuntu) Server at localhost Port 80
我需要配置我的routes.php吗？在安装指南中，它只说像这样编辑默认控制器$route['default_controller'] = "auth_lite/index";
顺便说一句，我对 CodeIgniter 很陌生。如果有人遇到这个问题，请帮助我。
在源文件中搜索“flexi_cart”，特别是在三个 *library.php 文件中，有一些字符串条目，必须更改为您自己的目录。
似乎适用于这种变化。
听起来您的 .htaccess 文件要么不工作，要么没有按应有的设置。
服务器正在寻找文件路径 /auth_lite/demo 它应该将该字符串传递给index.php.
这是 CI 最常见的 .htaccess 文件之一。试试看：
<IfModule mod_rewrite.c>
RewriteEngine On
# developing in a subfolder? (http://localhost/app/) change this to app/
RewriteBase /
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ 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 $1 !^(index\.php|images|robots\.txt|css|js|swf|wymeditor|galleries|ffeiliau)
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
试试看。
