[Theme: Black & White] Menu navigation not working & Mobile site wrong

Hi there,

My site is http://www.darlingbudsofmei.com

I noticed the other day when you type this into a mobile browser my site looks completely different event though I have a mobile responsive them and this shouldn’t happen.
Another thing I noticed is my top menu links (about/press/disclaimer) are all leading to my blog posts. I can’t understand how this happened as it was fine up until recently and I haven’t changed anything. When I look at my pages and menu settings everything seems normal!

Please help!!
