When you publish a site (or site changes) with our editor platform, the screen will prompt you with the URL for the published site.
YOU MUST CLICK ON THAT LINK TO THE SITE.
If you do not click on that link to the site, and instead close the prompt; thinking: "i just made the changes, i know what it looks like".. The editor will remain in a LIVE EDIT MODE. 
Live Edit Mode means that any further changes in the editor will be instantly published - which you likely wouldn't want. For instance, if you made more changes that you didnt want published yet, or if you were trying out something, or even had more editing to do but got called away in the middle of it.

If you accidentally click to close the prompt without visiting the site via the prompt's URL link, you can hit "publish" again and then click the link in the following prompt to disable the Live Edit Mode.
