subdomain failure with CI

[quote author="TheFuzzy0ne" date="1246117966"]Does the subdomain work when you access it directly from the address bar?[/quote]

No. You can not type or submit a form to dev.<mySite>.com. You can, however, submit or access the controller by using <mySite>.com/dev.

Can you walk me through the steps of how you, in the past, have created and used a sub domain?

So far, I I've only updated my config file and then created the sub domain through cpanel. Thats it...
