@jerry I think it might be all posts from [email protected]. Checked on kbin.social, works fine, but on Fedia I get a 500 error when visiting the magazine.

ETA: I also get a 500 error when trying to message a user from a different instance, even on the same platform (fedia.io -> kbin.social). This seems to be a platform bug, as trying to message this account from my kbin.social one results in me getting sent to home.

Found my first 500 error, at this URL: https://fedia.io/m/[email protected]/t/48041/rule-mp4

I think I'll switch back to Fedia for the time being, I mainly sought after kbin since everyone was flocking to it. But now knowing more how the Fediverse works, I think I'll return here.
