Mediavine Grow Social Plugin Conflict

I use the Mediavine Grow Social Plugin on Wordpress- there seems to be a conflict (according to Mediavine developers).

When I click on the Pinterest button on the left of my site, it shows only broken images, and tries to prompt me to “Ugrade to the new Save Button for Chrome”, but in reality, there is no upgrade. It’s just not reading the extension properly. From some googling, looks like this might be a hotlink protection issue. Ideas? TIA! [Sharing the Wander]
