你好，

我们一直在顺利使用“discourse-categories-suppressed”，隐藏了两个类别。当我们选择第三个类别时，控制台中出现了此错误，并且选择器已损坏。我们可以重置类别，但现在无法设置任何类别，只会出现此错误。

版本 0.1。

有一点需要注意，在插件列表中也无法禁用它。已禁用所有其他插件，但错误仍然存在。

可评分类别也受到影响，似乎任何带有“category\_list”下拉菜单的内容都已损坏。此外，主题标签下拉菜单也存在同样的错误。

安全模式无法解决问题，禁用插件也无法解决。

大家有什么可以尝试的故障排除方法吗？

这里似乎有一个类似的帖子。

它在这里中断了。

category-selector.js

actions: {  
onChange(values) {  
this.attrs.onChange(values.map(v =\> Category.findById(v)).filter(Boolean));  
return false;  
}  
}

我已经设法通过数字海洋 Discourse 镜像的新建干净版本复制了这一点。所以没有插件，只是在初始设置之后，所以这与插件无关，而是 Discourse 核心问题。

我目前在全新的 Discourse 安装中也看到了这个错误，我刚刚才设置好。它阻止了管理员区域中某些下拉菜单的点击。

鉴于你比我早几分钟遇到这个问题，我猜测是最近的某个更新导致了这个问题。你找到的链接是两天前的，这很吻合。

我只在我的新设置中看到了这个 bug，在我其他的网站上都没有。

很高兴（某种程度上）我不是唯一遇到此问题的人。我的服务器也是几天前才搭建的，这是我的第一次设置。

似乎是最近搭建的。
