How do I load an avatar for myself? I've gone to Settings --> Avatar, clicked Upload Avatar and selected an image I saved. But then I get the error message, "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data." I don't know what that means. I'm guessing that I'm violating the parameters of naming an image, and/or maybe the image's size or type? The image I was going to use is a .jpg. My only Fediverse account is this one, on startrek.website.
