<p>Backwards Compatible Permalinks helps prevent 404 errors when switching between permalink structures.</p>
<p>It achieves this by appending a set of backwards compatible post rewrite rules. This ensures posts are still accessible at their previous permalink after the permalink structure is updated.</p>
<h4>Example</h4>
<p>Let’s say your permalink structure is set to “Month and name” and you have a post titled “I Love WordPress.” That particular post would live at <code>https://example.com/2019/03/i-love-wordpress/</code>.</p>
<p>But what if you wanted to switch to the “Post name” permalink structure and have your post live at <code>https://example.com/i-love-wordpress/</code> instead?</p>
<p>You could but this would result in the existing post permalink 404ing when visited. Which is problematic if the previous URL was bookmarked or shared on social media.</p>
<p>With Backwards Compatible Permalinks installed your post would be accessible at both the old and new permalink structures:</p>
<ul>
<li><code>https://example.com/2019/03/i-love-wordpress/</code></li>
<li><code>https://example.com/i-love-wordpress/</code></li>
</ul>
<h4>Caveats</h4>
<ul>
<li>This plugin does not work retroactively. i.e. you must have the plugin installed and activated prior to switching permalink structures before backwards compatibility will work.</li>
<li>Currently only standard posts are supported.</li>
<li>Backwards compatibility is not supported between certain permalink structure updates. This is due to a clash between permalink structure regex matching.</li>
<li>Backwards compatibility is only provided between the most recent permalink structure update. i.e. you cannot change your permalink structure 3 times and have backwards compatibility across all 3 structures.</li>
</ul>
<h4>Deactivate or uninstall</h4>
<p>After deactivating or uninstalling this plugin please ensure you visit Settings > Permalinks in the WordPress admin area to flush your rewrite rules.</p>

<p>This is a plugin that will download a CSV of your urls, meta titles, and meta descriptions when you hit the button in the admin bar. It was built to help our SEO team assess the urls, and titles/metas inside the site. It requires an installation of <a href="https://yoast.com/wordpress/plugins/seo/" rel="nofollow ugc">WordPress SEO plugin by Yoast</a>.</p>


Thank you for using this bad ass plugin, that grabs the page urls, titles, and meta descriptions from a site running WordPress and Yoast SEO.
