Your theme uses jQuery version to 1.9. Version that removes some core functions, like the browser detection it had. Lots of older scripts use those.
Hm. I see that your theme is set to use the latest version available, so it breaks.
is there a way I can fix it?
Yeah, you must tweak the theme to load his available jQuery and not the latest one from google. Because you can’t update the rest of the plugins the same automatic way as Jquery.
