Mac OS X Server: Apache Web Service won't start

My Panther OS X Server-running iMac (long blog to come) was working wonderfully until I started playing around with the Aliases for my one and only site. After I did this, I noticed that it seemed to randomly create additional Aliases. I next noticed that my website was unavailable in Safari so I went back to the Server Admin app and found that the Apache Web Service wasn't running! I clicked 'Start Service' and it thought about for a moment and then simply brought up the 'Start Service' button again. I couldn't get my web server to run and I was starting to get a bit peeved. I rummaged the Internet and found someone suggesting that I try unchecking my website from the 'Sites' list in the Web Service config pane - I did this and tried loading the Web Service and it worked! Of course, with the website unchecked, it wasn't getting me very far in practical terms :) I chose to create a new site in the 'Sites' panel (with the same config as the old site, minus the Aliases) and clicked 'Start Webservice' - hey presto, I was back online!
