I am using the latest version of wordpress with the responsive 2015 theme. The drop down menu doesnt show on mobile - or when the browser window is very small. Its the drop down menu that is three lines. When you click it, it should have a drop down menu.
It works fine on a full desktop screen - but when I shrink the screen (or view it on mobile), the three lines menu does create a drop down. Nothing happens when you click it. Here is the link. Anyone have any ideas? Ive disabled cache
