<p>This plugin will look at another site you specify whenever a 404 error occurs and check if the requested path is there. If the path is found, it will redirect there rather than show the WP 404 page.</p>
<p>This is particularly useful to silently redirect over to an archival copy of a website when a major redesign has been done.</p>
<p>More information about this plugin can be found <a href="https://www.tenseg.net/software/404sitechecker" rel="nofollow ugc">on its homepage</a>.</p>
