Changing your link structure in WordPress can lead to all of your old links breaking and returning a “404”. But no more! If someone goes to an old link for your site, I’ll find the new link and redirect them there automatically.
No configuration. No one-by-one setting of the new link structures. No wrestling with complicated regex patterns. Just install me and relax.
Redirect 404s works with posts, pages, and custom post types (like ecommerce products).
<ul>
<li>Note – the plugin only works for permalink structures where the last “chunk” of the URL is the post name (also called the slug).</li>
</ul>

Redirect Old Links

Did you change your permalink structure and now have old links "404ing"? I'll redirect those old links to their new one for you.

This plugin allows you to use longer URLs (permalinks), by allowing much more characters in your titles and slug. The important is that this is done in a way that is future compatible with WordPress core updates. 
There is a 200 characters limitation on WordPress core nowadays and this limit is raised to 3000 with the plugin. 
Plugin is always extending the current WordPress core code – your long URLs will work even after WordPress core updates. 
This plugin is really useful especially in non-latin slugs because of the required url escaping that increases the length of your permalinks a lot.
<h4>Features</h4>
<ul>
<li>Upon activation the available slug length (post title) will become 3000, allowing long permalinks.</li>
<li>Required functionality is automatically applied without changing WordPress core files.</li>
<li>Even after core updates, plugin will automatically apply required changes and just keep your long URLs working.</li>
<li>Plugin requires at least MySQL 5.0.3</li>
</ul>
