我已经在现场设置了数十个CI项目，但之前从未遇到过这个问题。我上传了网站（/ demo），但是当我访问＆＃34; www.example.com/demo"时，我得到了一个空白屏幕。错误日志中没有错误。
我使用的.htaccess无疑是有效的，因为我上传的所有项目都是如此。
以下是它的编写方式：
<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>
在以前的项目中工作得很好。
我在cofig / config.php中做了
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO'; // tried REQUEST_URI too not working...
我认为这是服务器问题？ mod_rewrite也启用了。
