I’ve created a Maintenance page and it’ll show up when I enter my homepage but can I still work on my website. Can I see somewhere a demo of what i’ve created before. My point is, that I would like to have the website fully ready before showing it to the public.
If you want to actually block of the rest of your site you’ll need to use a plugin like http://wordpress.org/plugins/ultimate-maintenance-mode/ .
The blank page template isn’t a full lock down for the site and is just to act as a placeholder to prevent the main index from showing.
