3d book not working

I am trying to integrate this 3d book plugin on my site. I am having some problems.

  1. My navigation is not click-able, and have no idea why.
  2. My responsive-navigation is not showing up when i resize the browser.
  3. When the java-script from the theme is activated the plugin function “flip(se bagside)” is not working.

I am not that good with java-script, and therefor have problem finding what causes the problems. I have tried deleting stuff to narrow down what is conflicting, but need some help now.

The site is online HERE
