Add-on domain, where my Zen Cart is located, URL not showing

Zen Cart 1.3.8a; Database Patch Level: 1.3.8; From new install; Customizations are limited to graphics.
PHP Version 5.2.9; Server: Linux host49.hostmonster.com 2.6.28-9.16.intel.BHsmp #1 SMP Sat Apr 18 11:41:59 MDT 2009 x86_64. ; MySQL 5.0.75-community-log; Using Future-Zen template but changing the template makes no difference.
I have Zen Cart loaded on an add-on domain to my main domain. When the home page of the cart on the add-on domain is addressed, it looks perfect. When a sub-page is addressed inside the cart, the URL shows my main domain address. How do I get all sub-pages to strictly indicate the add-on domain URL? :frusty:
Main domain: https://www.bakerfoto.com
Add-on domain: https://www.ashahouse.net

Thanks

change you TWO configure.php files to reflect the .net site.

OK, I changed the TWO configure.php files by replacing all bakerfoto.com with ashahouse.net. What a mess. Could you be more specific about which lines need to change?

If you did all this, it should be working, unless you have some sort of redirect set up.
