Enable Error Logging in php-fpm

Edit your pool file

vi /etc/php/7.0/fpm/pool.d/www.conf

Add

catch_workers_output = yes
php_flag[display_errors] = on
php_admin_value[error_log] = /var/log/fpm-php.www.log
php_admin_flag[log_errors] = on

if you only enable “log_errors”, then errors go to default nginx error log.
