Issues with responsiveness?

I have a number of issues:

  1. My responsiveness is all messed up.

    I get grey areas all around my photo and a huge gap under the nav when I minimize.

  2. My nav bar is stuck on hamburger no matter how wide I expand the window on desktop.

Here is website.

Hello there,

It looks good to me on both mobile and desktop screen size.

Have you got it resolved yourself?
