About This Release
WP Rocket v3.19.2.1 is a patch update to v3.19.2, specifically designed to resolve urgent bugs and compatibility concerns affecting a subset of users. While no new features are introduced, this update is highly recommended for all users to maintain optimal site performance, caching reliability, and integration stability.
Key Fixes in v3.19.2.1
🔧 Critical: Fixed Cache Not Regenerating After Deployment
- Resolved an issue where static HTML files were not regenerating after site migrations or deployment hooks (e.g., from Git or staging environments).
- Ensures your site stays fresh and properly cached after updates.
🛠️ Compatibility with PHP 8.3 & 8.4
- Patched a PHP fatal error related to
array_key_first()usage in edge cases. - Full compatibility restored for PHP 8.3 and early 8.4 builds.
🌐 Cloudflare Integration Fix
- Addressed a bug where "Purge Cloudflare Cache" failed to clear CDN assets when using API tokens with restricted permissions.
- Now respects scoped tokens and logs detailed error messages for troubleshooting.
🧩 Conflict Resolution with Popular Page Builders
- Fixed a JS minification conflict with Elementor Pro’s popup editor, preventing layout shifts and broken previews.
- Improved compatibility with Divi Builder when dynamic CSS generation is enabled.
🐞 Other Notable Fixes
- Resolved incorrect cache clearing for multilingual sites using WPML and Polylang during post updates.
- Prevented double-loading of lazyload scripts when third-party themes already include native lazy loading.
- Fixed a rare race condition during cache preloading that could cause 503 errors on high-traffic sites.
- Corrected .htaccess rules for HTTP/2 Push to avoid header duplication.
