I am not able to get to a shipping page. The path should be http://www.gmint.org/store/shopping-cart/shipping
That gives a HTTPS: error URL not found on this server.
I just added a couple of products and activated our Authorize.net AIM to test purchase an item and I get this.
I have know idea or time to know how to fix this...
Must be live and working by the weekend for big donor demonstration.
