.htaccess错误404

Question

When I uploaded my sources to hosting server, it shows : error 404 Not Found.

In my local server it works perfectly.

Here is my .htaccess :

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /folder/index.php/$1 [L]

and my config :

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