Can you post the last 20 or so lines from your Apache error logs after you try to view the page? What distro and version of linux? of Apache?

We'll need to see your httpd error_log and also perhaps nagios.log.
Please recreate the error then submit the last 40 or so lines of both of those files.

Code: Select all
ls -l /usr/local/nagios/sbin/
ls -ld /usr/local/nagios/sbin/
