After the update of Wordpress 4.7.4 my theme 'sydeny'doesn't work!

After a Wordpress update to version 4.7.4 my theme is not working correctly. Scrolling is not possible and also buttons etc either. I was working with this theme and almost finished. Is there also an update for this theme to correct the problems I have right now?! And also cleaned my history cache etc in my browser and even after that it still doesn’t work!

PLEASE HELP!!
