Product Lightbox No Longer Works

Hey there, Woo peeps!

So, since 2.1.4, the product lightbox functionality hasn’t been working (when clicking on product image, opens in lightbox with Twitter and FB sharing functionality).

Yes, I have it enabled in the admin. And I’ve also read ALL the threads online about many many other users frustrated by this, and still, no answers forthcoming from Woo.

I have updated to the most recent WC version and STILL the lightbox functionality won’t work. I’ve tried reasonable tricks and hacks suggested in other support forums and nothing.

Please please can someone on Woo’s end help with this? When I had my client on the previously mentioned version all was well and I didn’t want to update, to preserve that functionality, but I can’t let a client sit on a very old plugin version, simply for a lightbox.

Please help?

Thank you!
