我的wordpress网站的Feedburner出错

这是我的Wordpress网站: https://noshdaily.com/

这个 https://noshdaily.com/feed/ 然而,当我尝试使用时,feed已经存在了 https://feedburner.google.com 我收到以下错误:

An error occurred connecting to the URL: internal error

之后,当我确认有效性时,它会把我带到这里: http://www.feedvalidator.org/check.cgi?url=https%3a%2f%2fnoshdaily.com%2f

并产生以下错误:

Not Found
The requested URL was not found on this server.

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

我该怎么解决这个问题?
