ＳＯＳ——网站突然挂了！

哪位大神帮忙看看我的网站（http://www.sinostoneltd.com）出什么问题了，今天上午８点左右还能登录，到下午就完全挂了，因为是看了@颜Sir和 @小易的WordPress之后自建网站，没有网管，先求助米问了，多谢大家了。

打开主页时显示如下：

The http://www.sinostoneltd.com page isn’t working

http://www.sinostoneltd.com is currently unable to handle this request.

HTTP ERROR 500

打开内页时显示如下：

Not Found

The requested URL /shear-connector/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
