我刚刚安装了 Xampp 并下载了最近的 Wordpress。我尝试更改任何主题，但出现以下错误
I just installed Xampp and downloaded the recent Wordpress. I tried changing any theme but I get the error below

有同样的问题。
谷歌搜索显示，在过去的几天里，许多其他人也遇到了同样的问题。
问题似乎是 WordPress 与 XAMPP 附带的新 PHP 8.0.0 版本不兼容。
目前的解决方案是卸载 XAMPP 并下载一个旧版本 (PHP 7.4.13)。可以在这里上车：https://www.apachefriends.org/xampp-files/7.4.13/xampp-windows-x64-7.4.13-0-VC15-installer.exe
