I have exactly the same issue:
Here’s a link in a page where it works perfectly: http://www.s203427580.onlinehome.fr/tomcharbit/
And here’s a product page where it doesn’t load: http://www.s203427580.onlinehome.fr/tomcharbit/product/chawan-blue-glacier/
If you have a solution that would be great!
Honestly, I tested severel lightbox, and this one is BY FAR my favorite, especially for the easy settings in WP. Thanks for your great job!!
