Can't save configuration changes

[crsg1]

Hi there, I'm trying to adjust some sitemap entry attributes, but when I click save the response of the browser is:

Not Implemented
The page you are looking for cannot be displayed because a header value in the request does not match certain configuration settings on the Web server.

Web Server at [ External links are visible to forum administrators only ]

What can I do?

Greetings!
