I'm wondering why I can't upload a profile picture. I've tried multiple times and the file size is within the limits set, but it keeps telling me "file upload failed". Does anyone know what I'm doing wrong? TY!

Or is a profile picture different from the avatar that appears under people's names? Because actually, thinking about it, there is a profile picture when you go to my profile. So I guess what I really mean is, how do I upload an avatar that will appear when I post? Thank you!
