Menu and icon links not working

[letsgofishing]

Can someone please check out http://www.logostore.co.za on a cell or tablet and tell me if the menu and icon links work.
I've been on this problem for nearly 10 hrs and am desperate. When I preview the site in XDPX all works as expected. There's a white strip at the top which is sticky and the menu and icons are on top of this - they are also sticky.
When I publish the site, the menu and icon links are dead - nothing happens!!!
I've attached only the 1st 2 "pages" (it's a scrolling website) - can someone please find out the problem.
Many thanks,
Mike


Stand by - the nav bar is no longer a nav bar!
Fixed that but still doesn't work - icons also
