Websites gone

I have looked on here and the internet but I can’t find anything were people are having my same issues.
This past updates I ran a couple of days ago all of my websites are now down. Not a single website will put now. I can’t seem to get them back up.
I’m running CentOs 5.8 32 bit


Are you getting an error of any sort when trying to access your sites?

Do any errors show up in the Apache logs, either $HOME/logs/error_log, or the system logs in /var/log/httpd/error_log?

Also, what does this command output:

rpm -qa | grep httpd
