Profile Banner not working - Plugin Error

[AlteredCarbonate]

Hello lads!

I've tried to add a Banner to my Profile.
I cropped it and tried to upload it.

Which results in a error
nodebb-plugin-s3-uploads-updated :: Missing credentials in config

I'm highly sure that's not intentional, and if yes.
Could you disable the function or give a hint?

Thanks!

EDIT:
@BrynnaDaRosa said in Can't upload cover photo on forum profile:

okay, wait, is the cover photo on the forums broken too?

Seems to be a duplicate.
