would anybody know where I could find the php_ini configuration file to look for error log, as my code will not work in wordpress. I went to app folder, then public folder, but only see wp_config.php there. I went into conf folder, then php folder which shows php.ini.hbs and php-fpm.conf.hbs files. I looked in the wp config.php file, but there is nothing about an error log there.
php --ini
at the command line. That list all the ini files that PHP reads, and is probably correct for mod_php unless you override settings in your web server config but I don't know if that's still the answer for FPM.
