I am having trouble opening Hamburger menu and the Youtube on description are not working. The website is: https://www.ngollc.com/
This is one example product page that video was not working: https://www.ngollc.com/products/015-05-komatsu-pc28uu-mini-excavator-s-n-2269
We modified the code a lot and have no idea what to fix now.
Help would be appreciated, thanks.
