此日志出现在report目录下，必须得修复。
1。进入数据库，core_config_data 表移除其中关于cookie及session的项，不用担心，如果删除错误，会自动调用默认的配置参数。
2.打开文件
/vendor/magento/framework/Session/SessionManager.php
部分版本报错的文件是
lib/internal/Magento/Framework/Session/SessionManager.php
具体依据您自己出错的日志来判断。
找到
// Enable session.use_only_cookies
ini_set('session.use_only_cookies', '1');修改为
if (!$this->isSessionExists()) {
ini_set('session.use_only_cookies', '1');
}找到
/**

* @return void
*/
private function initIniOptions()
