我发现了一些与此错误有关的参考
concrete5.org/community/forums/customizing_c5/…用户在哪里 描述了可能性的数量。但是需要帮助 无法理解我为什么要检查服务器设置的原因 我的错误以及我应该寻找什么
该站点具有多语言站点地图，但均不起作用。该站点当前的版本为“ concrete5-8.5.0”。
无论我能找到什么相关问题，都是与早期版本的Concrete 5有关，并且致力于解决该问题的更改已在该版本中存在
我找到的一些URL https://www.concrete5.org/community/forums/usage/cant-load-sitemap-error-msg-inetrnal-server-error https://www.concrete5.org/community/forums/customizing_c5/sitemap-no-longer-works-shows-and039internal-server-errorand039/ https://github.com/concrete5/concrete5/commit/2cf69ac90a8c8d1c7a451c9a82badf358cc74a1a
他们都没有指出我们这个问题的原因。如果有人可以帮助我指出问题的原因和解决方案，我将不胜感激。

解决方法
您能更具体一点吗？您说站点地图不起作用是什么意思？你看到了什么？浏览器的控制台或Concrete5的日志中是否有任何错误消息？
