Link won't open in lightbox

Hi all,

I have a link to a register button on my webpage, found here:

http://www.obedia.com

if you click on one of the “get started” buttons, you’ll get my registration form in a lightbox.

Thing is, this lightbox only works on the front page. It won’t work on other pages, such as this one:

https://www.obedia.com/ableton-live

Where if you click on the register button, the signup form opens in a new window, and it looks wonky.

I can’t for the life of me figure this out. I inherited some of this code form the past developer and I’m trying to clean some things up, and this is one of them. I can only assume that there’s a java call somewhere that I’m not catching, but I can’t see where it is for the life of me.

If anyone has any thoughts, I’d be really grateful. The only java lightbox code I’ve been able to find is in the header.php for this theme, and it doesn’t seem to change anything if it’s added to the page wherein the link doesn’t work.

Thanks very much.
