As long as the files are readable by anyone, the files being owned by root is OK. It has to be an Apache issue. The output you have provided did not show and output for running the status.cgi script.

Make sure that the nagios user account is still active and not expired. Run this to check it. chage -l nagios What is the user account you are using to login to the web interface? Is it setup in the cgi.cfg to access the system status data? Try editing the /etc/groups file and add the nagios user a...

Any other suggestions, ideas, or things to check?
