Popup/Lightbox doesn't ever load

I added it and I was able to use it, but when I try as a test user to click on my previous ticket, and the (I’m assuming lightbox) pop-up appears, it just spins, and spins, and spins. No content is every loaded in the window. If I close the window I then see the thread of the conversion of the ticket. I have tested this in both Chrome and Safari and I get the issue in both.

Here is what it looks like: http://imgur.com/89tDfAB and I’m using the Project AR 2 Theme, which you read more about here: http://www.arrastheme.com/project-ar2/
