详情介绍:
Anti-Cache Kit is a development tool for WordPress developers and designers who need to bypass all caching and optimization mechanisms during development, testing, or troubleshooting.
Development tool only. Do not leave active on production sites.
Key features
Cache and optimization management
- Automatically detects and flushes 16+ cache plugins
- Deactivates optimization plugins that interfere with debugging (Perfmatters, FlyingPress, WP Asset CleanUp, and more)
- Clears object cache (Redis, Memcached) and OPcache
- Clears hosting-specific caches (SiteGround, Cloudflare, Kinsta)
- Prevents browser caching for administrators
- Automatic timestamped backup of .htaccess before any modification
- Injects .htaccess rules to disable SiteGround cache via environment variables
- Sets no-cache, no-store headers at server level for all visitors
- Disables ETags and mod_expires to prevent conditional caching
- Sends CDN/proxy bypass headers (X-Accel-Expires, Surrogate-Control)
- Automatically restores original .htaccess on plugin deactivation
- Automatic timestamped backup of wp-config.php before any modification
- Comments out conflicting definitions with visible markers instead of deleting them
- Enables WP_DEBUG, WP_DEBUG_LOG, and SCRIPT_DEBUG (errors go to wp-content/debug.log)
- Disables WordPress cache (WP_CACHE = false)
- Safely modifies wp-config.php using WordPress Filesystem API
- Restores original wp-config.php from backup on plugin deactivation (plain copy, no processing)
- Timestamped backups are kept for reference until the plugin is deleted

常见问题:
Is this safe to use on a live website?
Yes, with caveats. PHP-level anti-cache measures only affect administrators. However, the .htaccess rules affect all visitors to ensure complete cache bypass. Use maintenance mode to show a status page to visitors during development. Always deactivate when finished.
Why does it deactivate optimization plugins?
Optimization plugins like Perfmatters, FlyingPress, and WP Asset CleanUp modify how CSS, JS, and other assets are loaded. During debugging, you need to see the unmodified output to identify issues. These plugins are temporarily deactivated. Reactivate them manually from the Plugins page when you are done.
What happens to my wp-config.php and .htaccess?
Both files are automatically backed up with timestamps before modification. When you deactivate the plugin, originals are restored from backup. Backups are kept for reference in the plugin's backup/ directory until the plugin is deleted.
Why does maintenance mode not show in incognito?
Version 4.0 injects .htaccess rules that disable server-level caching and sends aggressive cache-busting headers (including CDN and proxy bypass headers) to ensure the maintenance page is always served correctly.
Can I customize the maintenance page?
Yes. Use the ayudawp_anticache_maintenance_data filter to customize heading, status text, message, and retry text.
Can I add support for custom cache plugins?
Yes. Use the ayudawp_anticache_cache_plugins filter to add entries to the plugin list.
