Profile avatar won't change

I am trying to change profile avatar image on AwesomeBB by getting the image URL from the edit field. I do get image correct, that works. But when I try to apply it, nothing happens.

Code removed by author.

The whole idea is to go around the limit of 64kb avatar size. Use any image user provides for avatar and force it. But it doesn't work. It's applied on all pages.

EDIT: I fixed it
