Php SocialEngine4:通知错误：Zend Engine\u Api\u异常，消息项类型未知

我正在使用socialengine4，我的通知不断给我这个错误。我以为这是某种类型的配置，并查看了数据库或通知设置，但我一直无法修复此错误。谁能给我指出正确的方向吗

项目的设置位于应用程序->模块->模块名->设置>清单.php中

有一个名为items的数组，我在其中添加了“news\u content”，它起了作用。

我设法修复了它

问题在于（尽管模块列表中的模块框上缺少启用/禁用链接），它还是被禁用了

为了启用它，我访问了“engine4_core_modules”表，搜索“storage”名称，并将“enabled”单元格内容从0更改为1
