My Chem SE account is registered through my Google account. So obviously my Google profile picture was the one set for my Chem SE account as well. Few months earlier I had changed my Google profile picture and the change was in effect on this site as well. Everything was working fine until a few days earlier when my profile picture was replaced by a cross in the middle of a white background (indicating invalid I suppose), even when I had not messed with it at all (neither here nor in my Google account). I tried to update it several times it shows the change for a few seconds but when I close and reopen this site the cross comes up again. I tried clearing cache from my browser thinking that the problem is only with me, but recently I saw another user whose profile picture was the same cross as mine. So it might be possible that few more users are facing the same issues. Neither could I find any related information through previous question-answers on this iste. Though it doesn't hinder my participation here, but its irritating all the same.
So I would be very obliged if someone could explain what could possibly be going wrong, and provide some suggestions so that I can troubleshoot this issue . Any help is very much welcome.
