I've created a #SoloRPG community over on the #Lemmy instance https://lemm.ee. Lemmy is a #Reddit lookalike for the Fediverse. The community is available at https://lemm.ee/c/solorpg (the recommended way of accessing it), but it can also be followed from any Fediverse account by following @solorpg.

@hexedpress Hey. I created a solorpg community on lemm.ee, but I'm having trouble uploading a banner for it. Mine is the same dimensions (1200x514) and same format (.webp) as yours on @osr, but still I get a JSON error message when I try to upload it. Do you remember if you had to do some special trickery to get it to work?
