I have a website at http://www.landmhighland.com/index.php?main_page=product_info&cPath=41_58&products_id=461
The lightbox script seems to be starting without having clicked on anything, and without any reference image. It only does this on product pages.
Specifically, the overlay is appearing on the page, and the LightboxImage appears to be loading. When the image is clicked on, it redirects to the home page.
It seems to have started after modifying unrelated pages. I am not seeing any JS errors. Any ideas?
