Can you provide the snippet of your code that's not working?

import React from 'react';
import { render } from 'react-dom';
import App from './modules/App';
import Repos from './modules/Repos';
import About from './modules/About';
import { Router, Route, hashHistory } from 'react-router';

render(
  <Router history={hashHistory}>
    <Route path="/" component={App} />

    <Route path="/repos" component={Repos} />
    <Route Path="/about" component={About} />
  </Router>,
  document.getElementById('app')
);

I have this in my App.js and the code does not work for me when attempting to hit: http://localhost:8080/#/about:

Warning: [react-router] Location "/about" did not match any routes
