Anti-Cache Emergency Kit

Anti-Cache Emergency Kit is the ultimate tool for WordPress developers and designers who need to bypass all caching mechanisms during development, testing, or troubleshooting.

⚠️ Development Tool Only – Do NOT leave active on production sites!

Key Features

🔧 Comprehensive Cache Management * Automatically detects and flushes major cache plugins * Temporarily deactivates cache plugins during development (user can easily reactivate) * Clears object cache (Redis, Memcached) * Clears OPcache and hosting-specific caches * Prevents browser caching for administrators

🛠 Debug Mode Activation * Creates automatic backup of wp-config.php before any changes * Safely modifies wp-config.php using WordPress Filesystem API * Automatically enables WP_DEBUG, WP_DEBUG_LOG, WP_DEBUG_DISPLAY * Disables WordPress cache (WP_CACHE = false) * Shows PHP errors and warnings for troubleshooting * Automatically restores original wp-config.php on deactivation

🛠️ Maintenance Mode * Optional simple maintenance screen for non-logged users * Prevents visitors from seeing development errors * Quick toggle from admin bar * Customizable maintenance message

Admin-Only Impact * All anti-cache measures only affect logged-in administrators * Regular visitors see the normal cached site (unless maintenance mode is enabled) * Perfect for live site development

Smart Management Panel * View current status and active features * Easy one-click reactivation of cache plugins * Manual cache clearing options * Clear overview of what was changed

How It Works

  1. Backup: Creates automatic backup of wp-config.php
  2. Activation: Automatically flushes and deactivates all detected cache plugins
  3. Debug Mode: Enables WordPress debug mode and disables WP_CACHE in wp-config.php
  4. Anti-Cache Headers: Sends no-cache headers to admin users
  5. Asset Versioning: Adds random versions to CSS/JS files for admins
  6. Maintenance Mode: Optional simple screen for non-logged users
  7. Deactivation: Restores original wp-config.php from backup

Use Cases

  • Testing theme or plugin updates
  • Troubleshooting white screens or errors
  • Developing new features without cache interference
  • Checking design changes in real-time
  • Debugging PHP errors and warnings
  • Safe development on live sites

Security & Safety

  • Automatic backup of wp-config.php before modifications
  • All changes only affect administrator users
  • Automatic restoration of original configuration on deactivation
  • Secure nonce verification for all actions
  • No database modifications beyond options
  • Compatible with WordPress multisite

How to Test Plugin Features

After activating the plugin, verify each feature is working correctly:

Debug Mode Testing

  1. Check wp-config.php: Look for the debug constants added by the plugin
  2. Verify backup: Check /wp-content/plugins/anticache/backup/wp-config-backup.php exists
  3. Trigger a PHP error: Add <?php echo $undefined_variable; ?> to a theme file
  4. Verify error display: You should see PHP errors on the frontend (admin only)
  5. Check debug log: Look for /wp-content/debug.log file creation
  6. Test error logging: Errors should be logged to the debug.log file
  7. Check WP_CACHE: Verify WP_CACHE is set to false in wp-config.php

Cache Plugin Deactivation Testing

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

Browser Cache Prevention Testing

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

Object Cache Testing

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

Maintenance Mode Testing

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

Hosting Cache Testing

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

Overall Functionality Testing

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

Backup and Restoration Testing

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