Those console messages are not the issue, for a few of reasons I can be sure of.
The error path shows that these are messages from one of the hosting company’s ‘must use’ adminbar plugins. They are not of particular consequence, but more importantly this means that there are no console errors of any kind when not a user is not logged into an admin account or any account. There are no JS errors at all. But the light box problems still exists for composites and bundles.
The other point is that lightbox is working properly for the main product image you see at the top left (even with the console messages you highlighted). Just disable the ‘cursor’ and ‘pointer event’ CSS in firebug/dev tools for that image and you will see the lightbox work nicely.
