When a plugin update fails or your database server goes offline, most WordPress sites collapse into a broken white screen or generic server error. This hurts customer trust, interrupts sales, and can negatively impact SEO crawling. **FatalFlow** intercepts fatal PHP and database failures _before WordPress fully loads_, displaying a clean branded recovery page instead of a broken website. Perfect for agencies, WooCommerce stores, business websites, and production environments. ### Why FatalFlow? ### Protect Your SEO Rankings FatalFlow returns a proper: ``` 503 Service Unavailable ``` response with a `Retry-After` header — helping search engines understand that your site is temporarily unavailable instead of permanently broken. This helps reduce the risk of: – Google de-indexing – SEO ranking drops – Crawling issues caused by 500 errors ### Prevent the «White Screen of Death» Instead of exposing visitors to raw PHP fatal errors or blank pages, FatalFlow shows: – a professional maintenance screen, – loading indicator, – branded messaging, – modern glassmorphism UI. ### Works Even When WordPress Fails FatalFlow operates using: – MU-plugin recovery logic – `db-error.php` drop-ins – shutdown fatal handlers This means protection still works when: – plugins crash, – themes break, – database connections fail, – WordPress core cannot fully boot. ### Features Feature Details Fatal error protection Handles `E_ERROR`, `E_PARSE`, `E_CORE_ERROR`, `E_COMPILE_ERROR` Database outage recovery Automatic `db-error.php` deployment SEO-safe maintenance mode Sends proper `503` headers Zero dependency architecture Works without database or active plugins Lightweight performance No frontend slowdown during normal operation Beautiful recovery UI Modern dark glassmorphism maintenance screen WP-CLI aware Automatically skips handlers during CLI operations Safe cleanup Removes generated files on deactivation ### Technical Highlights * System-level recovery architecture * Early bootstrap interception * Automatic MU-plugin deployment * Database-independent rendering * Clean activation & deactivation flow * Minimal runtime overhead ## Installation 1.

During normal requests, performance impact is negligible. ### Can FatalFlow protect WooCommerce stores? Yes. FatalFlow is especially useful for WooCommerce and business-critical websites where downtime affects sales and trust. ### Does this replace a backup solution? No. FatalFlow is designed for graceful failure handling and SEO protection — not backups or disaster recovery. ### Will Google index the maintenance page? FatalFlow sends proper `503 Service Unavailable` headers with retry instructions, which tells search engines the outage is temporary. ### Does it work if WordPress is completely broken? Yes. FatalFlow uses MU-plugin and drop-in mechanisms that load before most of WordPress. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “FatalFlow – WordPress Fatal Error Recovery & SEO Protection” is open source software.
