My Menu does not work on small devices

I have a couple of other installs with Unos and they have been great. I checked them to see if they had the same issue and they do not.

I have tried other themes and the menu works. I have tried disableing all the plugins and the issue remains.

When viewing the site on a phone or tablet the small 3line menu does not opperate. You can tap on it and the area will blink like it wants to do something but it will not show the links to other pages.

The page I need help with: [log in to see the link]
