Using #WordPress with the #ActivityPub plugin and seems like it's not playing well with #W3TotalCache, as the author page that should return an ActivityPub author JSON for an author page, just being cached (not bothering about the "Accept" header).
Solved it by just exempting the `/author/.+` paths from caching, but it is not satisfying, the cache plugin should be able to handle these things.
Also, I have no clue whether it will make any difference for @gergely at all :P
And after poking around this area to see what the author page, #WebFinger plugin, the #Nodeinfo endpoint returns, a side-quest is now a deep-dive into an old-ish article from @Gargron to try start to piece things together
https://blog.joinmastodon.org/2018/06/how-to-implement-a-basic-activitypub-server/
(while still it is just nerding out, not sure if it will have any specific effect)
Now further rabbit hole of looking at various instance's Instance endpoint https://docs.joinmastodon.org/methods/instance/#v2, e.g. this very instance's: https://fosstodon.org/api/v2/instance but also others like @grafana's
https://grafana.social/api/v2/instance and discovering Mastodon Glitch edition https://glitch-soc.github.io/docs/
and a reminder of how images are blurred here for loading using #blurhash https://blurha.sh/ that looks pretty cool and would love to understand the process / see if it can be used well in code I maintain.
