Jupiter primary menu doesn't show on Chrome

I’m using Jupiter theme, all plugins and WP are up to date however the primary menu does not display on Chrome (safari works perfectly). I’ve tried it on both my Mac laptop and my android phone browsers and the same thing happens. Site is: drinkslowcow.com.au.

On the Mac Chrome the view looks like a broken link to an image…the little broken pic box appears and the word Slow Cow runs down the page in a very thin column (ie. one letter per row).

Any suggestions? Please note, I am an absolute beginner so if you can treat me like a 3 year old, I’ll probably understand.

Appreciate any help. Thank
