Codeigniter URL在live中需要index.php，而在localhost中一切正常

我已经在live中设置了数十个CI项目，但以前从未遇到过此问题。我在live（/demo）中上传了该网站，但当我访问“www.example.com/demo”时，我得到的是一个空白屏幕。错误日志中没有错误

毫无疑问，我使用的.htaccess对我上传的所有项目都是一样的

下面是它的写法：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /demo/

#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]

#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,
#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
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.

ErrorDocument 404 /index.php
</IfModule>

我认为这是服务器问题？mod_重写也已启用

你的实时服务器是windows吗？@kumar_v:不是。。它的linux..您是否尝试过在

$config['uri\u protocol']='AUTO'中使用
query\u string
？是。。我已经在我的问题中提到过。。不工作：（我说添加查询字符串，比如$config['uri\u protocol']='query\u string'；
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO'; // tried REQUEST_URI too not working...
