Here’s a quick guide: WP_DEBUG The master switch. When enabled, WordPress will display PHP errors, notices, and warnings. Required for the other debug constants to work. WP_DEBUG_LOG Saves all debug messages to /wp-content/debug.log. Essential for debugging issues that happen in the background (AJAX, cron jobs, REST API). WP_DEBUG_DISPLAY Shows errors directly on your web pages. Useful during development but never enable on production — it can expose sensitive information to visitors. SCRIPT_DEBUG Forces WordPress to use the development versions of core CSS and JavaScript files instead of minified versions. Helpful when debugging scripts. SAVEQUERIES Stores database queries in a global array for later analysis. Useful for identifying slow queries but adds overhead — disable when not needed. WP_DISABLE_FATAL_ERROR_HANDLER Disables WordPress’s “recovery mode” so you see the actual PHP fatal error instead of “There has been a critical error on this website.” 🤝 Support & Documentation Need help?
