Problem javascript theme

Hello,
Apologise I suffered for my english but I’m using google transalte for translation.
I Just Bought the theme “Game Addict” html version.
I modified the file locally (with the latest version of XAMPP) and everything works perfectly.
Now I loaded the theme on my site and unfortunately all the parts that require java codes do not work properly (parallax etc.).
This is the link of my site that you can check: http://www.battleriteitalia.it
I have successfully loaded all the folders, so I have not forgotten any files.

Could you tell me how to fix this error?
