Blaze Layout help

Hey guys I’m doing a tutorial on extending the users class,
Link to the tutorial
In every path I try, i always get a blank page, and i’m not understanding why.
Any help would be appreciated.
This is my routes.js file:

FlowRouter.route('/', {
   name: 'home',
   action: function() {
   BlazeLayout.render("mainLayout", {
      content: "home"
   });
  }
});
FlowRouter.route('/login', {
   name: 'login',
   action: function() {
   BlazeLayout.render("mainLayout", {
      content: "login"
   });
  }
});
FlowRouter.route('/register', {
   name: 'register',
   action: function() {
   BlazeLayout.render("mainLayout", {
      content: "register"
   });
  }
});

Check your console for any errors.

But i would guess that the templates either don’t exists or are not loaded properly.

The are no errors in the console, and the templates do exist.
Here is the repo if you want to have a quick look
