Lightbox now working

Hey,
here’s another “Lightbox not working” topic. I have read other topics but none of them have helped me. Switching to twenty twelve theme lightbox works but not on my custom theme so the problem is on my theme. Here’s a link to the website: https://www.tmimariannapere.fi/tuotteet/kirjat/kirja-albumi-testi/. I have wp_header and wp_footer set so that’s not the issue.
