你好，我按照客服给的提示从专业版pro 5.5.3回滚到开源版8.4.1，出现了数据库schema 的错误提示：
17:46:35 ERROR: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'order' in 'order clause'

我查了zt_branch, 这个表确实没有order 键，难道这个zentao的这个sql 语句有问题？
除此之外，产品和测试两个显示卡多个页面提示sql语句错误。管理员有疑问可以发信致我邮箱。恳请指导！

清除浏览器的历史、cookie等后，仍然出现该问题。
换一台电脑，发现默认用户名变为了另一个人，但也不是之前自己登录得用户，并且也是中文。
