Issues installing a 'dev copy' for editing
 

I have store that is already live that I need to make several changes to. Per instructions on the Wiki, I backed up my database via phpMA, and backed up my entire existing xcart install directory, as it is fairly heavily modified. I created a new database via mysql, imported my backup, and copied all the files over to the new subdirectory, I then changed all related info in config.php in the root of xcart. When I visit the dev cart and try to add a product it just redirects me to the cart is empty page, any suggestions?

EDIT**
Also modified htaccess and session id.

It also redirects me to the old shopping cart when I hit the buy now button on the home page.

**Double Edit
Found it, it was in auth.php in the cart root.

@include_once $_SERVER['DOCUMENT_ROOT'] . "/scartdev/top.inc.php";
