do you have profile cover photo plugin? if so, disable it

let me try

Can you change your avatar now?

yup but looking unprofessional 

Go here: www.yoursite.com/admin/user-profile and drag and drop avatar widget to Column1

i did it.. why width is too big ( white background where minic live icon and fav gift is present )

Provide screenshot of this page: www.yoursite.com/admin/user-profile

ju.jpg  check it 

you need to drag and and drop it in the column1 or 2 not the top content, this where the profile snippets or about me widgets are.  be more attentive

i checked all possible positions but it's same .. 

What do you mean you checked all positions, your avatar widget is in the top content area, which is why it takes 100% width of this area. have you tried to place it where other widgets are, where the about me widget is. It is clearly seen in your screenshot

only stable at this place .

That's right

okay !

This solution worked for me - thanks Ross - I also have the profile photo cover plugin.  I'd presume that we'll need the developer to sort this out on his end, yes?

Yes, correct. 

mark this post as sticky  @rose .

The error is gone, and you can choose from the existing photos ( library ) but then the icon just spins and spins, disappears and does nothing.  Is anybody else experiencing this issue?
