Not Working — Unable to See Why

Hi,

I have used and enjoy your plugin’s clean, dependable functionality in many sites built for my clients. In a recent site it’s just not working for WP galleries is it normally would:
https://instant-snow.com/our-products/

So far, I am at a loss to discern why.

The only unique thing I do see, is this:
When I do a normal view-source on a gallery page, I can clearly see the rel=”prettyPhoto[xxx]” added to each gallery item.
BUT — when I inspect the gallery line items in FireBug — they are not there.
I’ve never seen this happen before.

The site is pretty basic — built as a child of ElegantThemes.com Evolution Theme.

Any idea what could be causing this oddity in behavior, and ultimate failure of gallery images to load in prettyPhoto as expected?

Thank You,

XIMMBALO
