The main menu doesn´t seem to work for me. When I roll page down, the overlay-menu appears, but it disappears after I roll the page back up and doesn´t show in its location. I tried to switch to the classic-menu, but it didn’t work. Despite switching to classic menu, the overlay-menu is still visible and the problem with disappearing menu still exists.
I tried the theme on two different site and the problem appeared with both of them.
