Purges the full listing hierarchy 20i StackCache leaves stale when you edit a post (homepage, archives and feeds) and rebuilds it.

ABCode Improved Caching for 20i StackCache

<p>This is an add-on for <strong>20i StackCache</strong>, the cache plugin on 20i&#8217;s Managed WordPress and WordPress Optimised hosting. It fills a specific gap in how StackCache clears its cache.</p>
<p>When you publish or edit a post, StackCache purges only that post&#8217;s own URL. Every other page that <em>lists</em> the post (your homepage, its category and tag archives, custom taxonomy archives, the post-type archive, the blog page and the main feed) keeps serving the old, cached version until its cache naturally expires. So a new or updated post can be missing, or shown with stale content, on exactly the pages your visitors browse to find it.</p>
<p>This plugin closes that gap.</p>
<h4>What it does</h4>
<ul>
<li><strong>Purges the whole listing hierarchy on edit.</strong> On publish or update it clears the homepage, the post&#8217;s public taxonomy term archives, its post-type archive, its parent pages (for hierarchical content), the blog page on a static front page, and the main feed: everything StackCache leaves behind.</li>
<li><strong>Rebuilds what it cleared, if you want.</strong> If <a href="https://wordpress.org/plugins/abcode-cache-warmer/" rel="ugc">ABCode Cache Warmer</a> is also installed, the purged pages are handed straight to it and warmed back up immediately, so visitors never hit a cold page. Without the warmer, the purge alone still fixes the staleness, and the next visitor simply gets fresh content.</li>
<li><strong>Adds a &#8220;Purge This Page&#8221; control.</strong> A nonce-protected item in the admin bar on front-end views lets you clear a single page without clearing the whole site, plus a tidy &#8220;Purge Everything&#8221; option.</li>
</ul>
<h4>Safe by design</h4>
<ul>
<li>It does nothing at all unless StackCache is active: on any other host it is a silent no-op, and it tells you in the admin if StackCache is missing.</li>
<li>It never purges anything off your own domain.</li>
<li>It respects StackCache&#8217;s own settings: if StackCache is set to full-purge on every change, this plugin stands aside rather than issue purges nobody needs; and it never double-purges a URL StackCache already handles.</li>
<li>The purge runs in a short background task, never on your save request, so editing stays fast.</li>
</ul>
<h4>Who it is for</h4>
<p>Anyone whose WordPress site is hosted on 20i (or a 20i reseller) with StackCache enabled, and who wants edits to show up straight away across their whole site instead of lingering behind the cache.</p>
<h4>Who made this</h4>
<p>ABCode builds and maintains this plugin. If your 20i site needs more than a purge fix, we also do <a href="https://abcode.co.uk/services/wordpress-speed-optimisation/" rel="nofollow ugc">WordPress speed optimisation</a> as a service. The plugin stays free and complete either way.</p>
