I just joined and yeah I'm getting this too. Can't upload a profile avatar for me or for my community.
Just FYI: here's the error for trying to upload a user and community profile pic: {"data":{"msg":"Required command magick not found, make sure it exists in pict-rs' $PATH","files":null},"state":"success"}
Slightly different error when trying to upload a banner image for my community: {"data":{"error":"rate_limit_error"},"state":"success"}
