Hi there.
Do you mean you can’t see the site or the coming soon page/notice? The site: could be because the plugin is active.
The coming soon page/notice: I had the same problem. You can either switch it on and preview it or just preview it. Alternatively, log off and view it or use another browser (Firefox, internet explorer, chrome etc) or open a new tab in the incognito mode…you’ll be able to see it.
