Look for a comment at the very beginning of the HTML file, like this: <h3>Settings</h3>

<h3>Limitations</h3>
<p>Caching does not apply to:</p>
<pre><code>authenticated users;

the admin panel;

404 pages;

search pages (?s=...);

RSS feeds (/feed/);

AJAX requests;

POST requests;

URLs with GET parameters (except paged for pagination).<h3>Troubleshooting</h3>
</code></pre>
<p>Issue: the cache is not created.<br />
Solution: make sure that:</p>
<pre><code>define('WP_CACHE', true) is present in wp-config.php;
WordPress has write permissions for /wp-content/cache/mi13-cache/.
</code></pre>
<p>Issue: pages do not update after editing.<br />
Solution: manually clear the cache on the settings page.</p>
<p>Issue: access permission error when clearing the cache.<br />
Solution: check file permissions in the cache directory.</p>
<h3>Security</h3>
<pre><code>Permission check (manage_options) before clearing the cache.

Caching disabled for authenticated users.

Exclusion of system pages (404, search, feed, etc.).

Use of the secure WordPress API for file system operations.<h3>Directory structure</h3>
Cached files are saved in: /wp-content/cache/mi13-cache/

Each file has the .html extension and a name corresponding to the page URL.

<h3>Privacy</h3>
<p>Holographic Extreme Cache does not collect analytics, does not track visitors and does not send site data to a third-party service.</p>
<p>The plugin stores cache files, configuration helper files, generated WebP image files and optional log files inside the WordPress uploads directory. Logging is off by default.</p>
<h3>Uninstall</h3>
<p>The plugin can remove its settings, cache files, configuration files, log files and scheduled events on uninstall if the uninstall cleanup option is enabled before uninstalling.</p>
<p>If uninstall cleanup is not enabled, settings and generated files are left in place so the site owner can remove or inspect them manually.</p>
<p>Generated WebP image files are not automatically removed unless the plugin uninstall cleanup process specifically handles them. This helps avoid removing media files that may still be referenced by the site.</p>
