I’m getting lots of

```plaintext

We renamed this file on latest, it is meant to unregister the old one

Is this causing issues?

No, I’ve noticed a lot of 4xx’s in the detailed traffic report which made me curious.

I’m pretty new to Discourse, so I wasn’t sure whether I should do anything about it. If it’s supposed to be that way (at least temporary) all is fine.
