Please help, i can't change profile avatar. I try remove profile avatar and then upload new avatar. But after 10minutes old avatar is back.

This is a known issue and you'll have to wait for some time in order for the changes to propagate.

The avatar does revert to the original but after about an hour or so - you'll see the picture that you've uploaded.

S-a schimbat si totodata inrautatit problema cu avatarul . Acum cand vrei sa iti adaugi un avatar nu ti-l mai incarca deloc.
