Hi Gavin,
I’m also developing an Arras-themed site with the WP e-commerce plugin and am having issues with my /product-page.
I’ve updated the /wp-content/themes/arras files with the additional .css and .php e-commerce files, but when navigating to the /product-page/ in my browser nothing is found or displayed, despite the /checkout/ and other pages working properly.
I would love to end up with something similar to what you’ve done with qtcards.com. Any help would be appreciated!
Thanks,
David
