I changed my photo, then realised that I had accidentally used a rectangular one with black bars. Tried to replace it with a square version, and the page would load for a bit after I pressed save, but the only thing that would actually change is the "Choose file" box would display "No file chosen" instead of the name of my file. Even when I tried to replace my image with the default Voat Goat, the same thing happened. The most likely cause is that the servers are overworked, but I was wondering if it was a bug.
Update: Logged on this morning and I now have a black background (as opposed to the usual white background) Voat Goat. Odd. Am still unable to change the photo to anything else.
