Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.

Edit the file /usr/local/cpanel/3rdparty/etc/phpmyadmin/php.ini

session.save_handler = sqlite
session.save_path =/var/cpanel/userhomes/cpanelphpmyadmin/sessions/phpsess.sdb

To

session.save_handler = files
session.save_path = /tmp

2) Function.session-write-close error
