Hello all. I have a problem with changing my avatar. For some reason, the first time I tried to upload my new pic, my PC reported that the connection was not trusted and dangerous and recommended me to leave. I know that this isn't true so I simply ignored it and went on. Strangely, my avatar didn't change. I tried again. This time, no "dangerous connection" warnings popped up, but my avatar still remains the default no icon. I tried 3 different browsers (I.E., Firefox, and Chrome) but nothing worked.
