Tried to fix mobile post

[ Moved to the Fixing WordPress sub-forum. ]

Hi,

I am having an issue with my most recent blog post, “Don’t Be Stupid; Don’t Quit Your Day Job,” appearing on mobile devices. It did on the desktop (http://realbrowngirls.com/theblog/). I updated my theme (BeTheme) in hopes that it would resolve the issue. When I did that it completely eliminated my navigation bar! Some people have told me that the navigation bar still appears on their browser. It doesn’t on mine (I have cleared my cache and tried Chrome, Firefox, and IE). The nav bar is also inactive on mobile. Everyone concurs that the nav bar is inactive on their mobile device. If anyone can help me it would be great! Thank you!
