Here seems to be the problem Link.js:124:

this.context.router.push(_location);

@taion is correct. The problem is this: https://gist.github.com/bodokaiser/8482e0932fe242967c8f#file-app-index-js-L45:L47. The Link components are used outside the context of the router and will not be able to access your browserHistory object. The Link component needs to be used in a children component of the Router. You should be able to use Link from your Home, About, Contacts components since they are children components of the Router. If you need to handle route changes outside the scope of the router you can pass the browserHistory and call browserHistory.push(path). This is best described here: https://github.com/reactjs/react-router-tutorial/tree/master/lessons/12-navigating

Yes this is the solution - however it is easy to forget or to not see the problem so it is good that this is now some sort of resource to this problem.
