Recent Sharify plug-in issues using Spirit theme

Hi.
I've been using the Sharify plugin smoothly and without incident for many months with my Spirit theme. In the last few days the Sharify bar has gone wonky. THe plug-in is up to date, and I just deactiveated then reactivated it, but the issue persists. The share bar now appears four times on my page! Twice at the top above the headline(!), once where it should--at the bottom of the post--and then again in the footer all smushed up on the left. (I took screenshots.)

I don't know where the error lies. Could it be related to recent WPMU update? Any help would be appreciate. Thank you!
