<p>An easy way of telling apart different installs of WordPress ( e.g. live/production/local ) via the admin bar. Super admins see a colour coded machine name in the admin bar, with an IP submenu. Mobiles will see a colour coded square dot</p>

<h3>How to Test Plugin Features</h3>
<p>After activating the plugin, verify each feature is working correctly:</p>
<h4>Debug Mode Testing</h4>
<ol>
<li><strong>Check wp-config.php</strong>: Look for the debug constants added by the plugin</li>
<li><strong>Verify backup</strong>: Check <code>/wp-content/plugins/anticache/backup/wp-config-backup.php</code> exists</li>
<li><strong>Trigger a PHP error</strong>: Add <code><?php echo $undefined_variable; ?></code> to a theme file</li>
<li><strong>Verify error display</strong>: You should see PHP errors on the frontend (admin only)</li>
<li><strong>Check debug log</strong>: Look for <code>/wp-content/debug.log</code> file creation</li>
<li><strong>Test error logging</strong>: Errors should be logged to the debug.log file</li>
<li><strong>Check WP_CACHE</strong>: Verify <code>WP_CACHE</code> is set to <code>false</code> in wp-config.php</li>
</ol>
<h4>Cache Plugin Deactivation Testing</h4>
<ol>
<li><strong>Before activation</strong>: Note which cache plugins are active in Plugins page</li>
<li><strong>After activation</strong>: Verify cache plugins are deactivated</li>
<li><strong>Check admin notice</strong>: Should list which plugins were deactivated</li>
<li><strong>Visit settings page</strong>: Go to Tools > Anti-Cache Kit to see deactivated plugins list</li>
<li><strong>Test reactivation</strong>: Use the “Reactivate All Cache Plugins” button</li>
</ol>
<h4>Browser Cache Prevention Testing</h4>
<ol>
<li><strong>Make a CSS change</strong>: Modify your theme’s style.css</li>
<li><strong>Hard refresh</strong>: Ctrl+F5 or Cmd+Shift+R should show changes immediately</li>
<li><strong>Check page source</strong>: Look for random version numbers on CSS/JS files</li>
<li><strong>Verify headers</strong>: Use browser dev tools to check for no-cache headers</li>
<li><strong>Test as visitor</strong>: Log out – visitors should still see cached version</li>
</ol>
<h4>Object Cache Testing</h4>
<ol>
<li><strong>Install Redis/Memcached</strong>: If using object caching</li>
<li><strong>Check cache status</strong>: Use Redis CLI or monitoring tools</li>
<li><strong>Verify clearing</strong>: Cache should be flushed when plugin activates</li>
<li><strong>Manual clear</strong>: Test the “Manual Cache Clear” button in settings</li>
</ol>
<h4>Maintenance Mode Testing</h4>
<ol>
<li><strong>Enable maintenance</strong>: Go to Tools > Anti-Cache Kit and enable maintenance mode</li>
<li><strong>Test as visitor</strong>: Open an incognito/private window and visit your site</li>
<li><strong>Verify maintenance page</strong>: Should see the maintenance screen</li>
<li><strong>Test as admin</strong>: Logged-in admins should bypass maintenance mode</li>
<li><strong>Quick toggle</strong>: Use the admin bar toggle for quick on/off</li>
</ol>
<h4>Hosting Cache Testing</h4>
<ol>
<li><strong>SiteGround users</strong>: Check SG Optimizer cache is cleared</li>
<li><strong>Cloudflare users</strong>: Verify Cloudflare cache is purged (if plugin installed)</li>
<li><strong>Manual verification</strong>: Check your hosting control panel for cache status</li>
<li><strong>Performance testing</strong>: Use GTmetrix or similar to verify cache clearing</li>
</ol>
<h4>Overall Functionality Testing</h4>
<ol>
<li><strong>Make theme changes</strong>: Modify CSS, PHP, or JavaScript files</li>
<li><strong>Check immediate visibility</strong>: Changes should be visible without hard refresh</li>
<li><strong>Test error display</strong>: Broken code should show errors immediately</li>
<li><strong>Verify admin-only</strong>: Log out to confirm visitors see normal cached site</li>
<li><strong>Check HTML comments</strong>: Look for “AyudaWP Anti-Cache Kit” comment in page source</li>
</ol>
<h4>Backup and Restoration Testing</h4>
<ol>
<li><strong>Check backup creation</strong>: Verify backup file exists after activation</li>
<li><strong>Note original wp-config.php</strong>: Take note of original configuration</li>
<li><strong>Deactivate plugin</strong>: Deactivate Anti-Cache Kit</li>
<li><strong>Verify restoration</strong>: Check that wp-config.php is restored to original state</li>
<li><strong>Backup cleanup</strong>: Verify backup file is removed after successful restoration</li>
</ol>
<h4>Testing Checklist</h4>
