## 説明

This simple plugin permanently redirects all 404’s to the main blog URL. There may
be several reasons why you might want to do this, but the primary purpose is to 
siphon Google Page Rank (TM) from missing pages to the homepage.

## インストール

The installation process is very basic:

 1. Upload the unzipped plugin folder to the `/wp-content/plugins/` directory
 2. WordPress の「プラグイン」メニューからプラグインを有効化してください
 3. That’s it!

  Do I have to configure anything?

Nope. The plugin is ready to go once you install it.

  Can you give me some examples for why this plugin may be beneficial to me?

Sure!

Example #1: If you acquire a pre-owned domain (that you intend to run WordPress 
with), you might not want to recreate every page that was part of the original site.
Alternatively, you might not want to build an exhaustive list of 301’s either. Enter
the 404 Redirection plugin. Now, you’ll never have to worry about not salvaging 
every drip of link-juice.

Example #2: Let’s face it, having an exuberant amount of 404’s is bad form. Search
engines might consider your site “broken”, and drop your rankings.

Works perfectly, as expected. I moved the site to another domain and decided not
to copy some pages – error 404 appeared. The solution is simple and simple installation.
I will slightly correct my comment. The first time I applied this plug-in was the
version of WP 4.4, I recently tried another version of WP – 4.7.2. – The plugin 
works exceptionally well.
