Register Pop-Up doesn't work

Hello, I need your help with this issue:

cart and login pop up work right

I´ve have already updated gk register and template

Hi,
regsiter is working as it should. In this template you are redirected to register page.

ok thanks. I thought that was a standard feature and it worked like eSport does.
