How to Test Plugin Features
After activating the plugin, verify each feature is working correctly:
Debug Mode Testing

Check wp-config.php: Look for the debug constants added by the plugin
Verify backup: Check /wp-content/plugins/anticache/backup/wp-config-backup.php exists
Trigger a PHP error: Add to a theme file
Verify error display: You should see PHP errors on the frontend (admin only)
Check debug log: Look for /wp-content/debug.log file creation
Test error logging: Errors should be logged to the debug.log file
Check WP_CACHE: Verify WP_CACHE is set to false in wp-config.php

Cache Plugin Deactivation Testing

Before activation: Note which cache plugins are active in Plugins page
After activation: Verify cache plugins are deactivated
Check admin notice: Should list which plugins were deactivated
Visit settings page: Go to Tools > Anti-Cache Kit to see deactivated plugins list
Test reactivation: Use the “Reactivate All Cache Plugins” button

Browser Cache Prevention Testing

Make a CSS change: Modify your theme’s style.css
Hard refresh: Ctrl+F5 or Cmd+Shift+R should show changes immediately
Check page source: Look for random version numbers on CSS/JS files
Verify headers: Use browser dev tools to check for no-cache headers
Test as visitor: Log out – visitors should still see cached version

Object Cache Testing

Install Redis/Memcached: If using object caching
Check cache status: Use Redis CLI or monitoring tools
Verify clearing: Cache should be flushed when plugin activates
Manual clear: Test the “Manual Cache Clear” button in settings

Maintenance Mode Testing

Enable maintenance: Go to Tools > Anti-Cache Kit and enable maintenance mode
Test as visitor: Open an incognito/private window and visit your site
Verify maintenance page: Should see the maintenance screen
Test as admin: Logged-in admins should bypass maintenance mode
Quick toggle: Use the admin bar toggle for quick on/off

Hosting Cache Testing

SiteGround users: Check SG Optimizer cache is cleared
Cloudflare users: Verify Cloudflare cache is purged (if plugin installed)
Manual verification: Check your hosting control panel for cache status
Performance testing: Use GTmetrix or similar to verify cache clearing

Overall Functionality Testing

Make theme changes: Modify CSS, PHP, or JavaScript files
Check immediate visibility: Changes should be visible without hard refresh
Test error display: Broken code should show errors immediately
Verify admin-only: Log out to confirm visitors see normal cached site
Check HTML comments: Look for “AyudaWP Anti-Cache Kit” comment in page source

Backup and Restoration Testing

Check backup creation: Verify backup file exists after activation
Note original wp-config.php: Take note of original configuration
Deactivate plugin: Deactivate Anti-Cache Kit
Verify restoration: Check that wp-config.php is restored to original state
Backup cleanup: Verify backup file is removed after successful restoration
