Allows you te set a page to be used as the 404 page. In order for the plugin to work you need to make some modifications to the <code>404.php</code> file in your theme. I set it this way so that the 404 page could be formatted to fit the theme, or can be set more dynamically.

Although this plugin will work with WordPress 2.8, it’s better suited for version 3.x.

Colorlib 404 Customizer is exceptionally easy to use and it does not require custom coding or technical skills. All the customizations for the 404 page are done strictly through the Live Customizer.
All websites usually come with a default 404 page already included, but it looks a bit more professional if you customize your own. Not all visitors know what the 404 error message stands for so you could even replace it with a friendlier and more proficient one. Even if it would be ideal not to have errors on your website, you cannot escape 404 errors which make 404 pages important.
