Not able ot view hosts/services in the Trends.cgi link

I'm running out of ideas myself and your problem seems to be unique. Try running the trends.cgi from the command line as the nagios user --

su - nagios
bash
cd /path/to/nagios/sbin
export REQUEST_METHOD="GET"
export QUERY_STRING="input=gethost"
./trends.cgi

You should see a lot of HTML but in that should be a listing of your hosts. You may see error information so be on the lookout for it. This will at least move us in the direction of eliminating apache as a problem.

I'd also re-verify my installation against the documentation.
