【问题描述】：

我最近将我的网站迁移到新的 AWS ec2 linux 实例。 Php8.0、MySql8.0，所有页面都正常。 Wordpress数据库从Mysql5.7导出，导入到MySql8.0。博客显示和 Wordpress 的其他部分工作正常。但是当我点击“添加新帖子”时，我收到了这些错误。 WordPress 是最新的 5.9.3。

如果我禁用 my.conf 中的错误，页面将进入无限循环并最终显示“网关超时”。

【问题讨论】：

您的 mu 插件可能是原因...阅读错误。
感谢您的回复。 mu 插件文件夹中只有一个插件'endurance page cache plugin'。我重命名了文件夹并检查，来自耐力缓存插件的那 2 个错误消失了，但所有其他错误仍然存在。看起来像变量初始化问题，因为 mysql8.0 。不确定 Wordpress 5.9.3 是否兼容 MySql8.0

【解决方案1】：

我从服务器上完全删除了 WordPress，并使用 WPEngine 插件将我的 WordPress 网站迁移到新的托管服务器。幸运的是，我仍然可以访问旧服务器和网站文件，所以我可以做到这一点。一切正常。

【解决方案2】：

我认为这是一个 PHP 版本问题。尝试切换到 PHP 7.4
