I am stuck with github pages. After publish I get blank pages. https://mikewarakom.github.io/mwanalytics

I did following:

1. Followed below procedure:
2. modified package.json:

 "version": "0.1.0",
 "homepage": "https://mikewarakom.github.io/",
 "private": false, 

3. Added basename into browserRouter

function App() {
 return (
   <ParallaxProvider>
     <BrowserRouter basename={process.env.PUBLIC_URL}>
       <PageRoutes />
     </BrowserRouter>
   </ParallaxProvider>
 );
}  

I would very appreciate some guides, thank you.
