A plugin to temporarily disable your website front-end and display a message 
to your visitors while still allowing back-end access. This plugin can be 
enabled or disabled with one click and also supports using your own custom 
HTML/CSS output for the splash page so you can make it as simple or as custom 
as you need it to be.
This plugin is especially useful if you need to temporarily make your site 
unavailable to your visitors. For example, you’re working on a new blog or 
website and you want to show a temporary “coming soon” page to your visitors 
while you’re working on it; or you’re fixing major bugs that would disrupt the 
user experience and need to make the front-end temporarily unavailable; or any 
other reason that you would need to make your website temporarily unavailable.
This plugin can be configured to allow admin users (you) to still be able to 
view the front-end while the splash page is enabled. If other users need to be 
able to review the site, you can enable authenticated users and/or specific IP 
addresses to be able to bypass the splash page as well.
<h4>Common uses for this plugin:</h4>
<ul>
<li>Displaying a splash page while you develop your blog or website</li>
<li>Temporarily making your site unavailable to visitors while you fix bugs, etc</li>
<li>Disabling a site if a client refuses to pay (we’ve all been there)</li>
</ul>
