phpMyAdmin - Error Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.
I face this problem in CentOS 6 with nginx and php-fpm, so I solve using this way
sudo mkdir /var/lib/php/session sudo chown nginx:nginx /var/lib/php/session sudo chmod 777 /var/lib/php/session
The restart both service
service nginx reload service php-fpm reload
Done.
