Hi Amin, I don't know whether I've found a bug in the software or it is related to my browser/OS in my computer. I tried to change my avatar picture and can't do that, so it seems. Symptoms: First I tried to change the pic with Safari browser, just selected new picture to be used as avatar, I get flash upload completed. I select okay, and old avatar remains in place Then I first deleted the old avatar. Selected new one, again 'Upload completed', selected okay, and old avatar popped up, strange Then I thought maybe it is the browser cache, changed to Firefox, same procedures, same results = can't change the avatar System: OS X 10.11.3 El Capitan Safari 9.0.3 Firefox 42.0 What could be wrong here?
