That fixed it for me, too! Thanks!

At some point a couple days ago, I stopped being able to update icons or banners on communities. I’ve tried everything I can think of on my side, including appointing a friend as a mod, who was also unable to edit the images.

[EDIT] I had both English and Undetermined selected somehow, and as per user suggestion I fixed that, and it worked! I can now update images, I just had to select ONLY undetermined.

Done, thank you very much again for your help!

That’s a good suggestion, thanks! …unfortunately I already tried that, up to and including deleting the current images completely to just start from scratch, and the UI won’t let me. I even tried deleting the community - and learned that there’s really no such thing(?) When you delete a community apparently it stays in the database as a deleted community, and only you can un-delete it. Not sure if that’s a temporary thing, or if it’s permanent, but in either case deleting that community didn’t allow me to make a new one with that same name. All I could do is un-delete it, and my problem persisted.
