【已完成】查看面板入口时报错Permission denied

当我把Linux面板升级为7.9.7，再打开面板提示我“请使用正确的入口登录面板”。我没有记下安全入口的8位字符，所以在SSH终端输入/etc/init.d/bt default后，报错：

/etc/init.d/bt: line 17: cd: /www/server/panel: Permission denied
cat: /www/server/panel/BT-Panel: Permission denied

注意：初始密码仅在首次登录面板前能正确获取，其它时间请通过 bt 5 命令修改密码

我不知道如何解决，请各位帮帮忙

您好，请使用root权限执行bt命令
