Plone Multilang 站点地图是空的

Question

在激活 plone.app.multilingual 的情况下运行 Plone 5.0.5 版我注意到站点地图行为异常。

如果我转到 mysite.com/en-gb/sitemap，我会得到该语言的站点地图 View ，很好。

如果我转到 mysite.com/en-gb/sitemap.xml.gz，下载并解压缩文件 .xml 文件，我会得到一个空站点地图(请参阅下面的文件内容):

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">
</urlset>

如果我访问 mysite.com/sitemap.xml.gz，我会得到相同的站点地图。控制面板

我已经尝试检查“语言”部分，但我在那里看不到与站点地图相关的任何内容。我当然确保在“站点”中勾选了“Expose sitemap.xml.gz”。门户目录

我尝试清除并重建目录，但无济于事。collective.linguasitemap

尝试安装它，但我认为它不适用于 Plone 5.0.5。当我尝试在这个 Plone 5.0.5 站点上安装它时，buildout 一切顺利，但在尝试加载我的客户端时我得到以下信息:

我们还有一些其他的 Plone 5.0.5 站点仍然可以毫无问题地创建 sitemap.xml.gz 文件。它似乎只影响安装了 multilang 的站点。

有什么明显的我做错了吗，或者任何人都可以阐明这个问题吗？

提前致谢!
