PHP 将我的 WordPress PHP 版本升级到 8.0.25 后，script-loader.php 出现致命错误

Question

将我的 PHP 版本从 7.4.33 升级到 8.0.25 后，我无法访问我的 WordPress。

当我尝试访问它时，我看到以下消息：

This page isn’t working
ohayotourism.com is currently unable to handle this request.
HTTP ERROR 500

以下是我的错误日志：

添加： 尝试将 $value{0} 的两次提及更改为 $value[0] 但没有成功。
