For quite some time, until very recently, this link worked
[topicspage]: {{< ref "tags/topics" >}}
It produced a list of all the pages with this in their headers:
tags:
- topics
I’m not sure why it stopped working across all my sites. I wonder if there is a better way to do this.
I’m afraid this is related to this, but that seems never to have worked, while my lists only just stopped working.
