I'm having problems installing chili-light2. I am using version 1.1.6 of zenphoto.

I downloaded the theme, unzipped it, loaded onto the server, and activated it in the admin panel. Everything seems to load fine, it's just that when I click on a thumbnail, it just opens the image by itself. No lightbox effect.

Am i doing something wrong?

Here's a link to the gallery:

You need to either upgrade to the latest build:

Or apply the fix to your theme:
