Error: Could not read host and service status information!

Error: Could not read host and service status information!

I had been running Nagios 1.2 for over a year with no problems, but the
system it was running on crashed and with only a backup of the configuration
files, I have been building a new Nagios system.  This is on SUSE 9.1.

I went through the instructions step by step and everything seemed to go
smoothly, but none of the .cgi screens will come up.  Instead I get the
"Error: Could not read host and service status information!" message.

Here's what I've checked and what I know so far.

There are no errors in the nagios or apache2 logs.
Nagios itself is working. I am getting the correct notifications in my
e-mails

Here are the ps -ef lines for the running apache2 and nagios applications:
wwwrun    9371  9368  0 09:32 ?        00:00:00 /usr/sbin/httpd2-prefork -f
/etc/apache2/httpd.conf
nagios    9397     1  0 09:32 ?        00:00:00 /etc/nagios/bin/nagios -d
/etc/nagios/etc/nagios.cfg

(Nagios was installed in /etc/nagios to match the directory setup of the
previous installation)

Here are the Alias lines from httpd.conf:
ScriptAlias /nagios/cgi-bin /etc/nagios/sbin
<Directory "/etc/nagios/sbin">
   AllowOverride AuthConfig
   Options ExecCGI
   Order allow,deny
   Allow from all
</Directory>

Alias /nagios /etc/nagios/share
<Directory "/etc/nagios/share">
   Options None
   AllowOverride AuthConfig
   Order allow,deny
   Allow from all
</Directory>

(I have also tried variations by adding/removing the trailing / with no
effect.)

Here are the important lines from cgi.cfg:
main_config_file=/etc/nagios/etc/nagios.cfg
physical_html_path=/etc/nagios/share
url_html_path=/nagios
use_authentication=1

All of the paths in nagios.cfg are correct.

/etc/passwd
wwwrun:x:30:8:WWW daemon apache:/var/lib/wwwrun:/bin/false
nagios:x:1001:100::/home/nagios:/bin/bash

/etc/group
nagios:x:101:nagios1,wwwrun,nagios,nobody
nagiocmd:!:1001:wwwrun,nagios,nobody

Here are the permissions on the appropriate directories:

------------------

So far, nothing I have tried has made any difference.  Does anything stand
out to anyone that could be causing the problem?  I have checked all the
newsgroups I could find, and google, and nothing has budged the problem in
the slightest.

Any advice would be appreciated.
