 * Hi [@duffhugo](https://wordpress.org/support/users/duffhugo/),
 * This means you don’t have a valid SSL certificate. Really Simple SSL is not an
   SSL certificate, but a plugin to help you configure your site for SSL. Your hosting
   provider can install an SSL certificate for you.
 * If you want to revert back to http, please deactivate the plugin from the WordPress
   plugins overview, or follow these instructions:
