如果我启用了永久链接，我对自定义帖子类型“草稿”帖子预览重定向到网站主页有问题。

例如，我创建一个新的“项目”，另存为草稿，然后单击预览。预览窗口将打开到站点主页。

如果我将site permalinks设置为“default”，它将正常工作。

这是我注册帖子类型的代码。根据register_post_type codex entry, 我尝试了“query\\u var”（真/假/“projects”）的不同设置，但没有任何不同。我还尝试编辑重写参数和/或将其全部删除。不行。谢谢你的帮助！

UPDATE: 我已经确认，这是过去的工作，并打破了最近的更新。我猜这是register\\u post\\u type codex页面的“Public\\u queryable”部分提到的对4.2.2的更新，但直到刚才才有人注意到。
