+==== Debug error in nginx with php-fpm ====
+You set it per pool, inside: **/etc/php/8.x/fpm/pool.d/www.conf**
+<code>
+[www]
+................
+catch_workers_output = yes
+php_admin_flag[log_errors] = on
+php_admin_value[error_log] = /var/log/php8.2-fpm.log
+</code>
+Then restart PHP-FPM
+Example Before vs After
+  * Before (catch_workers_output = no):<code>
+[10-Nov-2025 10:30:21] WARNING: [pool www] child 12345 exited on signal 11 (SIGSEGV)
+</code>👉 You only see a generic signal crash.
+  * After (catch_workers_output = yes):<code>
+[10-Nov-2025 10:30:21] WARNING: [pool www] child 12345 said into stderr: "PHP Fatal error: Uncaught Error: Call to undefined function get_header() in /var/www/html/wp-content/themes/flatsome/page.php:12"
+</code>
+✅ Now you can see the exact file and line that crashed WordPress.
+🛠️ Combine With These for Full Debugging, Inside the same pool file or your **php.ini**:<code ini>
+log_errors = On
+error_reporting = E_ALL
+display_errors = Off
