FatalFlow – WordPress Fatal Error Recovery & SEO Protection
Professional-grade fatal error protection for WordPress websites.
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.
