Heh... you're not alone on that one. I had one of our IT techs call me one day to help him troubleshoot the problems with his new Apache install. Same thing. Installed Apache2, but started up 1.3. It happens. Don't beat yourself up too bad.

Last week I contacted tech support at my web host to find out why a particular theme was no longer available for the web based email. Answer: that theme is only available for Internet Explorer, not Mozilla/Firefox. Damn! I knew that, I've been using the same server app at work for nearly 7 years.
