Google button stopped working

Love this plugin and you’ve done a great job thinking through everything that’s needed when creating it. Kudos for that!

For some reason the Google + button stopped working suddenly.
I can use all the other like and share buttons but when I click the google+ nothing happens.

Any help would be much appreciate. I have the latest version of this plugin and wordpress.
