在某些时候某些网页会出现下面问题
顶部出现
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@j-query.org and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
下面的网页正常，奇怪的是过几分钟这个网页可能又正常了，可能其他网页又有问题了，这问题该怎么解决了？
