Redactor/HTMLPurifier 不允许条目更新 CraftCMS

问：

我对这一切相当陌生......你们能帮我弄清楚这里出了什么问题吗？

我的网站大部分都很好。但是，当我尝试编辑 Redactor 字段时，出现错误

Class 'HTMLPurifier_AttrDef_HTML_ContentEditable' not found

如果我按“保存”，它只会给我一个工艺风格的内部服务器错误页面

从工艺的 web.log 文件中堆栈跟踪...尝试在我的生产服务器（DigitalOcean、RunCloud）上保存条目时会发生这种情况。在我的开发堆栈（Lando）上工作正常
