virtue mobile not working

Hi quite new to this so any help appreciated, when I click on a product on my mobile the product won’t open but goes to accessories section. Is this an issue with jquerie mega menu or something else & whats the fix please. I would also be interested in finding out how to adjust the spacing on the nav bar so its all on one line on the main site
