I've made changes to max_upload_size in /etc/php5/fpm/php.ini and restarted both nginx and php5-fpm services. phpinfo() states that /etc/php5/fpm/php.ini is being loaded but after reloading/restartinb both services, max_upload_size remains unchanged.
Question: A server reboot solved the problem. Why is a reboot required? Did I miss out anything when restarting the services?
