This might sound really dumb, but I keep getting this message:

"It does not appear that this was submitted from the proper form."

when I tried to update my profile with a new avatar (it's 80x80, it's png.

I guess it might just pop up the moment I submit this message. But what am I doing wrong?

edit: nevermind, I figured it out - I had to change one thing at a time, not everything at once! I changed the site -submit- then signature -submit- then avatar -submit- and it worked!
