Openwebmail的问题

wgranger

我在RedHat 7.2下安装了open webmail 后，运行后通过验证提示我是第一次使用该系统然后让我设置，点击确定后出现以下提示
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to　complete your request.
Please contact the server administrator, root@localhost and inform them of the　time the error occurred, and anything you might have done that may have caused　the error.
请问各位，问题出现在什么地方？

我用的是Apache+Sendmail+Open webmail,用sendmail能收发邮件

谢谢各位
