i have checked ownership, but its still giving the same msg.
Here is part of my configuration file as pertains to the swap file:

cache_dir ufs /var/cache/squid 100 16 256
cache_swap_log /var/cache/squid/swap.log

If the cache and logs directory permissions are correct, then it's a SELinux problem
To verify if that's the case you can disable SELinux temporarily, running
Code:
setenforce 0
If that solves your problem, then you must read how to use configure SELinux policy for squid.

Hi Bathory
disabled SElinux with the command you gave me, and now squid is complaining about something else. right now am researching on the SElinux policy for squid that you mentioned. This is the msg i'm getting now:

Sep 11 13:40:10 localhost kernel: audit(1252669210.103:108): avc: denied { read } for pid=3917 comm="squid" name="00" dev=dm-0 ino=1180657 scontext=root:system_r:squid_t:s0 tcontext=rootbject_r:var_t:s0 tclass=dir

Are you sure SELinux is disabled? Because this is a SELinux message!!!
Make sure squid is not running.
Disable SELinux
Try to start squid without rebooting and see what happens.

squid was running, so i stopped squid 'service squid stop'
then i disabled SElinux, and then attempted to start squid and it gave the same complaint:

I think that you don't get those SELinux messages anymore. Those in you logs are almost an hour before the last squid stop/start.
You can stop/start again squid and watch the logs from another terminal with "tail -f logfile" to see if you get these messages.

The startup logs look OK. You can use ps to see if squid is running.
Code:
ps -ef|grep squid

You should consider the following:
Upgrade Fedora to a recent version, as version 5 is deprecated.
Read the SELinux documentation and see how to configure it, so it allows squid run smoothly and keep your system secure.
