Getting Error 404 message when click on Google+ icon

Hi there,
I deleted one of my Google+ accounts (trying to change my primary email address so as to keep my personal email out of Google+ for Kiwi Earth Mother – but no joy). I’ve changed the url for Google+ and it’s working via social media feather, but not through the Mantra icon, and I’m not sure why. Can anyone help please?

Many thanks
Sharon
