使用友链模板，点击友链会报出服务器错误500

[alsdhkauuhw]

是什么版本出现了此问题？

1.2.2

在线站点地址

https://www.jiewen.run/links

发生了什么？

使用主题的友链模板后，在菜单点击会报出500 Internal Server Error

相关日志输出

GET https://www.jiewen.run/links 500 (Internal Server Error)

附加信息

/links 这个路由是默认路由，自定义页面选择模版后，应避开这个路由，否则会冲突，可以选择/friends等其他

[alsdhkauuhw]

/links 这个路由是默认路由，自定义页面选择模版后，应时尚这个路由，否则会冲突，喜欢/朋友等

我避开也是不行，上面填的站点是主题的演示站点，上面的友链也崩了，应该不会是我设置的问题，相同模板的留言板是好的

你给的地址，现在用的是stack2 ，这个主题没有写links路由的模板，所以是错误的，跟joe无关。https://www.jiewen.run/friends

如果，再不行，可以提供下log日志

[alsdhkauuhw]

上面是我的运行日志，linkFinder似乎并没有被正确的传递到模板上，希望对问题的解决有帮助

[jiewenhuang]

你的友链有分组吗，创建个分组看看

[alsdhkauuhw]

我的友链是一个使用了友链模板的自定义页面，你所说的分组是指什么呢？能否详细说明？此外或许可以在模板中添加空值检查，以确保在分组数据为空时不会引发异常。
