Unable to start Web Sharing

Hi,

I've been slowly working through the O'Reilly Apache tutorial:

Unfortunately I think I've may have made an error with httpd.config because now Web Sharing isn't starting and the access_log and error_log isn't recording anything for the time I'm trying to start Web Sharing. I don't think I have a backup of httpd.config

Does anyone have a suggestion how I can debug and fix my problem?

Thanks for any help.

I've solved my own problem.

There's a default httpd.conf that I used to replace the broken one.
