Background video and tab not working after update

I just updated the theme using the method delete theme and install new theme per pinned post.

What I noticed is that, post update the video background that i was using on the main home page is not loading in Chrome whereas its loading in Safari.

Also in Chrome the tabs are not working and all tabs values are just opened up and not restricted within the designated tabs. This is also only in chrome and not in safari. Its working fine with Safari.

To check my claim I just took an online snapshot using a website and here is what it looks like now.

I need quick help as am planning to publish the website tonite.
