404页面找不到错误在服务器上，而它在本地机器上工作正常
下面在我的.htaccess中

RewriteEngine on
RewriteCond $1 !^(index\.php|(.*)\.swf|forums|images|css|downloads|jquery|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?$1 [L,QSA]

下面是config.php中的base_url代码

$root=(isset($_SERVER['HTTPS']) ? "https://" : "http://").$_SERVER['HTTP_HOST'];
$root.= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
$config['base_url'] = $root;
