Error: Could not read host and service status information

[Marc Powell]

Would you be willing to send ls -al's on ~nagios/etc and ~nagios/var as
well as the user/group that nagios and your web server run under? It
does sound like it might be a permissions issue and another set of eyes
can't hurt. Additionally, do you see and 'could not update' errors in
nagios.log?
