You are right.

You create the Addon Domain from within Cpanel, which we have done but isn't as easy as that.

Once you have added the Addon you should be able to access it by just typing the address addon.com into the browser address bar, but that is not happening, you have to address it as a subdomain.

I am currently talking to a guy employed by Cpanel on their forum, he told me to change the path to the Addon so that it was below the public_html folder, but that doesn't work. In the actual Cpanel documentation it tells you to place the Addon inside the public_html folder, so where do you go from there.
