[Plugin: WP jQuery Lightbox] Only works in compatibility mode for i.e. explorer

Hi, I am wondering if someone can help me figure out what the issue on this particular site might be https://betterwebsitebuilders.com/tetoncabins – lightbox only works on explorer (8 or 9) if compatibility mode is enabled. The plugin seems to be find on other sites so I’m sure my problem is related to this site alone. I have tried activating the default wp theme but that doesn’t solve the problem so I’m thinking I’ve got something else going on. any ideas?
