HTTP server authentication PROBLEM

Hi
I have a problem, when I clik on a service of NSClient++ for more info appears this error:

It appears as though you do not have permission to view information for this service…
If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI
and check the authorization options in your CGI configuration file.

I understand that there are access problems I have also checked the file but unfortunately I could not solve the problem.

Help

try checking the apache log and see if there’s some more info about which file you are not authorized to view.
