Hi thanks for a great plugin!
We are in the process of upgrading an old wordpress site... we have replicated the old site onto a subdomain for testing environment.. and have upgraded to latest verions of both WordPress and WP-Ecommerce.
Last step, I need to fix the checkout process by updating the Gold Cart add-on, to enable Authorize.net (old version of Gold Cart on replicated site will not show authorize.net as possible payment to choose).
We have downloaded the latest version of Gold Cart, and removed old version of Gold Cart. However when I activate the newest version of Gold Cart - the whole set breaks!! Just a white screen.....
Is this due having the same API key on both sites simultaneously? How can I test the site like this? I don't want any downtime to actual URL.. please help!!!
