Web Hosting Setup

Since the Samurai addon for Shopp uses an onsite checkout process, sensitive information (such as credit card numbers) will be entered on your website. In order to protect your customer’s information, your website’s hosting service will need to have SSL Setup|setup to support SSL. Setting up SSL will require an SSL certificate for your website. You can buy SSL certificates from the Shopp Store.
