I don't know exactly because i never tried updating my profile avatar before but when he said that it worked after previously trying, I suspected it must have been with an issue I deal with anytime I try to post 8,000+ characters on the coli. basically the site server rejects the POST request and you get a 500 internal server error. so because I posted frequently I realized that some posts of the same length weren't going through while some were and a few years ago I tried repeatedly pressing the post button and sure enough after a dozen or so clicks the post went through so i think it's an issue with how the server is configured. this thread is over 3 years old and it would be wild if that was the same posting error that was causing avatars not to be uploaded on first attempts.
i think it's a timing issue so if you keep pressing the post button in
rapid succession you'll eventually get the request to go through.

edit :
I might be right about the "solution" to he problem since the error was mentioned back in January 2023.
