我正在将当前的Eduma主题更新为最新版本（3.0.9.1），目前的版本是3.0.7。我正在运行WordPress 4.7.5。

但是，在运行更新时，我得到Update Failed: Internal Server Error 安装过程中的消息。所以我启动了这个过程，它运行了一分钟，然后它就停止了工作，我陷入了维护模式。所以我必须手动删除.maintenance 来自我的服务器的文件。

我截图了我在错误中看到的内容。

我在WordPress网站上运行了调试模式，这就是我所拥有的

这是主题本身及其组成部分的问题吗；还是我的服务器有问题？如果这是我的问题，我应该如何解决这个问题？

试图接触Eduma是一次可怕的经历，但收效甚微。此外，这不是我第一次在更新Eduma主题时遇到问题。
