URL Problem Please Help!

Ok, I set up a new site (same as always) But here is the problem.
If you go to the site with this URL

http://mafia13.com/ (works fine)

This URL

http://www.mafia13.com ( does not work)

Any help would be great
Thank you in advance.

you need to add a www alias under your apache config file.

 

Ok, Would that be in the script or on the server?
Thank you

This will be in your web server settings.

 

Thank you
I will see If I can find it.

Also, you need to do the same in named conf.
