用域名进入出现错误

测试地址：
http://kaixin888.net/（错误）
http://kaixin888.net/home/（可以）
http://kaixin888.net/home/index.php（可以）

错误网页出现的提示：
Warning: include_once(./common.php) [function.include-once]: failed to open stream: No such file or directory in D:\wwwroot\kaixin888\wwwroot\index.php on line 7

Warning: include_once() [function.include]: Failed opening './common.php' for inclusion (include_path='.;C:\php5\pear') in D:\wwwroot\kaixin888\wwwroot\index.php on line 7

Fatal error: Call to undefined function sreadfile() in D:\wwwroot\kaixin888\wwwroot\index.php on line 44

请高手指点， 测试号：123456  /  123456
大半夜了，该休息啦

自己解决了，替换index.php 就搞定
