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 ## 安裝方式 1. Upload the `fatalflow` folder to `/wp-content/plugins/` 2. Activate the plugin from the WordPress admin dashboard 3. Navigate to: Settings FatalFlow 4. Configure: 5. * Brand name * Accent color * Recovery message ## 常見問題集 ### Does FatalFlow slow down my website? No. FatalFlow only activates its recovery logic during fatal failures. 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. ## 使用者評論 這個外掛目前沒有任何使用者評論。 ## 參與者及開發者 以下人員參與了開源軟體〈FatalFlow – WordPress Fatal Error Recovery & SEO Protection〉 的開發相關工作。 參與者 * [ coderalamin ](https://profiles.wordpress.org/coderalamin/) [將〈FatalFlow – WordPress Fatal Error Recovery & SEO Protection〉外掛本地化為台灣繁體中文版](https://translate.wordpress.org/projects/wp-plugins/fatalflow) ### 對開發相關資訊感興趣？ 任何人均可[瀏覽程式碼](https://plugins.trac.wordpress.org/browser/fatalflow/)、查看 [SVN 存放庫](https://plugins.svn.wordpress.org/fatalflow/)，或透過 [RSS](https://plugins.trac.wordpress.org/log/fatalflow/?limit=100&mode=stop_on_copy&format=rss) 訂閱[開發記錄](https://plugins.trac.wordpress.org/log/fatalflow/)。 ## 變更記錄 #### 1.0.0 – 2026-05-08 * Initial public release * Added fatal PHP error recovery handler * Added database failure recovery UI * Added SEO-safe 503 maintenance responses * Added automatic MU-plugin and db-error deployment * Added branded glassmorphism recovery screen ## 中繼資料 * 版本 **1.0.0** * 最後更新 **14 小時前** * 啟用安裝數 **少於 10 次** * WordPress 版本需求 ** 5.9 或更新版本 ** * 已測試相容的 WordPress 版本 **6.9.4** * PHP 版本需求 ** 7.4 或更新版本 ** * 語言 * [English (US)](https://wordpress.org/plugins/fatalflow/) * 標籤: * [database error](https://tw.wordpress.org/plugins/tags/database-error/)[fatal error](https://tw.wordpress.org/plugins/tags/fatal-error/) [recovery](https://tw.wordpress.org/plugins/tags/recovery/)[seo](https://tw.wordpress.org/plugins/tags/seo/) [white-screen-of-death](https://tw.wordpress.org/plugins/tags/white-screen-of-death/) * [進階檢視](https://tw.wordpress.org/plugins/fatalflow/advanced/) ## 評分 這個項目尚無任何評論記錄。 [Your review](https://wordpress.org/support/plugin/fatalflow/reviews/#new-post) [查看全部使用者評論](https://wordpress.org/support/plugin/fatalflow/reviews/) ## 參與者 * [ coderalamin ](https://profiles.wordpress.org/coderalamin/) ## 技術支援 使用者可在技術支援論壇提出意見反應或使用問題。 [檢視技術支援論壇](https://wordpress.org/support/plugin/fatalflow/)
