Grey bar on top of my page?

[InLhings]

On my website: https://www.locusapplication.com, there's a grey bar above my navigation bar at the top of every page. It seems to be a part of the header image, but I don't know how to get rid of it.

@InLhings: seems you have installed some APP.  That may be causing it.
