Can I use Woo Commerce with HTTP?

No, with Woo Commerce you need an SSL (Secure Socket Layer) Sertificate (HTTPS).

To use SSL on your website, you need to buy an SSL certificate. Many providers sell certificates, all ranging in price; your hosting provider may also sell certificates.

The certificate is set up on your server, usually by your host. Once set up, you can access your store via https://yoursite.com — your browser may show a ‘lock’ icon in the address bar to show it is secured.
