For some reason the link has now changed back to the original.
To clarify – in case it helps:
The desired link is/was: https://anthesis.se/2021/07/06/aterhus-syns-dn/
The active link was: https://anthesis.se/2021/07/06/aterhus-syns-i-dn/
and could be seen in this screenshot: https://d.pr/i/8rca3B
It must have been a crazy long server cache or something because it has resolved itself this morning.
If it was something else, keen to hear what may have caused it though!
Thank you for your help anyways
