That was my first thought too but to no avail.
That's not my homepage, this is the home page: https://www.oruspace.co
When I enable/disable the bar the background image shifts, which suggests to me that the bar is there, but hidden behind the nav.
UPDATE: I can see it in mobile and tablet but not on desktop, and it is below the nav.
- The problem to solve is to get the bar to appear in desktop proportions, secondly for it to appear above the nav.
