您可以在此处找到问题：https://staging-v2.storna.app 管理门户工作 https://staging-v2.storna.app/admin API 也有效

只有着陆页有问题..它之前工作正常。

可能是什么问题？

日志中只有 2 个问题。其中 1 个是警告，另一个只是 php7 通知。所以我怀疑是不是因为这个。

Answer 1

您似乎使用的是 2.0.40 版本，这已被报告 here。似乎问题只存在于 PHP 版本 7.1 - 7.4 上，因为 PHP 8.0 似乎已成功通过，原因是

您可以将 composer.json 中的 minimum-stability 设置从 stable 更改为 dev，以及 运行 composer update 以更新您的yii 框架到 dev-master。

或者您可以仅从此 commit

手动更新这些文件

我会使用第二个选项，因为第一个选项也会更新所有包。
