Why is the editor running on http?

Since you’re developing on localhost without SSL and we include an iframe of that to enable our side by side editor or sandbox environment for plugins for you we need to run in on http. You can however switch to https at anytime, which will result in your plugin or website being not included as it is restricted by browser security, except you setup SSL on your local development environment as well. The same rule applies if you’re previewing your website in the side by side editor of Storyblok, there we will automatically redirect your editors to the right protocol.
