Getting Subdirectory contents to display in a browser

[erothoff]

I am a little afraid to modify things without knowing what is going on. I want to make some or all subdirectories to have all the contents of the directory visible. For example:

www.rothoff.biz/rick

should show all of the files in the directory. Right now, I get
403 Error- Forbidden!

It looks like thread:
http://www.howtoforge.com/forums/showthread.php?t=23990

has a solution for every domain on the server, but I don't want it system wide, just for the www.rothoff.biz domain.

Any suggestions?
Thanks,
Eric
