## 説明

Gatekeeper allows administrators to take a WordPress site offline quickly and easily
while leaving it fully accessible to administrators and other authorized users. 
Site visitors will be shown or redirected to a specified offline page. An optional
blacklist can be used for permanent bans.

** Features **

 * Visitors can either be redirected to an existing non-WordPress offline page (
   using http 302 temporary redirect) or WordPress pages can be temporarily replaced
   with the offline page.
 * Logged in admins can be whitelisted
 * The current admin’s IP address can be automatically whitelisted
 * An IP-based whitelist that can accept specific IP addresses, wildcards, and ranges
 * A basic IP-based blacklist that redirects blacklisted IPs to a specified page(
   not to be used for security)
 * A notifier that appears on administrator pages when the site is offline

## FAQ

  Installation Instructions

 1. Upload `gatekeeper` to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Go to _Tools > Gatekeeper_ to manage Gatekeeper.

  Why was this plugin developed?

I needed a “coming soon” page for a site I was working on but also needed to be 
able to use WordPress myself in order to test themes, designs, etc.
 The existing
landing page themes are nice, unless you also need to be able to test a theme without
letting the world see. At first, I added some PHP code into the WordPress index.
php file to redirect all but my IP address to the coming soon page, but WP upgrades
opened my site to the world. Editing the htaccess file is an option, but it’s extra
work and only works until my IP address changes. So…I created Gatekeeper.

  Can I redirect visitors to an existing WordPress page?

No. Gatekeeper protects all WordPress pages (except admin and login pages) from 
everyone but those whitelisted, so redirecting to a WordPress page
 would create
an undesirable redirect loop.

  How do I use an offline page?

The offline page can be any web-friendly page: HTML, PHP, text, etc. It’s not required,
but recommended, to keep this file in a separate directory to keep it from being
confused with WordPress files.

  Can Gatekeeper protect non-WordPress pages?

No.

  Should I rely on the Blacklist for security?

No. The primary purpose of the plugin is to take sites offline for maintenance. 
The Blacklist was designed as an extra feature to help thwart connections from undesirable
IP addresses, but is not designed as a security feature. WordPress administrators
would be advised to use Wordfence, iThemes Security, Bulletproof Security, Sucuri
Security, or another widely used and trusted WordPress security plugin for security.

  Help! It doesn’t work!!

If the plugin doesn’t appear to be working, first check your whitelist. Make sure
you’re not testing from a whitelisted IP address. If _Auto-Protect Admin IP_ is 
checked, the plugin will attempt to automatically whitelist your IP address and 
let you see the site normally. If you have _Whitelist Logged-in Admins_ checked,
the plugin will let you view the site normally as long as you are logged into WordPress.
The plugin is designed to do its best to not lock you out of your own site.
