Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at C:\Program Files\Minds\GraduateWeb\global\default.php:13) in C:\Program Files\Minds\GraduateWeb\global\config.inc on line 4

奇怪，奇怪，我在我的电脑上用session就可以用，可是不知道为什么上传到服务器上就出现这样的问题，怪啊怪，想不懂。我看了同样是放在服务器上的一个网站，他们却可以实现，不过很乱，不太明，麻烦高手指点下啦
