Counter not working anymore

The counter suddenly isn’t working anymore on our site. FB shows ‘12,88M’ shares for all posts and Twitter gives ‘11,6K’ for all posts. Doesn’t make any sense.

Already reinstalled the plugin. Didn’t fix the problem unfortunately.

Do you know what’s happening?

**************

Just found out: when you click on the Sharify Facebook-button benath the articles, a popup window appears and lets you share http://www.google.com (so not the url of the article). That’s probably why the amount of shares is so high.
