将php配置文件php.ini 中的 session.auto_start = 0 改为 session.auto_start = 1

重启服务器 然后提示

找到phpmyadmin/libraries/session.inc.php 大概（92行）

PMA_fatalError('Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.');

注释掉就ok了
