Hello, I have installed nagios on solaris 10. By default the local host is monitored and everything works fine. But when I try to access the Trends, statusmap,alert histogram from the web interface I am having the below error. I checked all the permissions and every thing looks fine. <h1>Internal Server Error</h1> The server encountered an internal error or misconfiguration and was unable to complete your request.
