Angular UI-Router View Not Displaying Anything

I can't get UI-Router to work, which is really annoying because I'm building a site off of another site I built where it was working fine. Currently, ui-view is not displaying anything, and ui-sref links are not clickable or redirecting. I'm not getting any errors either. My code is below. Any help would be much appreciated!

JS: app.js

var app = angular
    .module("RssTransfers", ["ui.router"])
    .config(MainRouter);

    function MainRouter($stateProvider, $urlRouterProvider) {
        $urlRouterProvider.otherwise('/');

        $stateProvider
            .state('transfers', {
                url: '/',
                templateUrl: 'transfers.html',
            })

            .state('about', {
                url: '/about',
                templateUrl: 'about.html'
            })

            .state('upload', {
                url: '/upload',
                templateUrl: 'upload.html'
            })
    };

HTML: index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <title>RSS Transfers</title>

<body ng-app="RssTransfers">

    <div ng-include="'navbar.html'"></div>

    <div class="wrapper" ui-view></div>


</body>
</html>

dummy text to display: transfers.html

<div ng-controller="TransferController as transfer">
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Commodi, est, cum. Dicta, eius obcaecati quia culpa ipsam quibusdam tempore adipisci molestias optio, nam corporis, veritatis voluptatem incidunt cumque a sequi?</p>
</div>

As requested, here's the code for the controller:

TransferController.js

angular.module('RssTransfers')
    .controller('TransferController', TransfersController);

TransfersController.$inject = ['$http'];

function TransfersController($http){
    var self = this;
    self.all = [];
    self.addTransfer = addTransfer;
    self.newTransfer = {};
    self.getTransfer = getTransfer;

    getTransfers();
    function getTransfers(){
        $http
            .get('http://localhost:3000/transfers/')
            .then(function(response){
                self.all = response.data.transfers;
        });
    }

  function addCriminal() {
      $http
          .post('http://localhost:3000/transfer', self.newTransfer)
          .then(function(response){
              getTransfers();
    });
    self.newTransfer = {};
  }

}

Solution

I've taken your code and created a plunkr here. Note - that it doesn't contain the controller just yet.

angular.module('RssTransfers',['ui.router']);

(function() {
  'use strict';

  angular
    .module('RssTransfers')
    .config(routing);

  routing.$inject = ['$stateProvider', '$urlMatcherFactoryProvider', '$urlRouterProvider'];

  function routing( $stateProvider, $urlMatcherFactoryProvider, $urlRouterProvider ){

    $urlMatcherFactoryProvider.strictMode(false);

    // For any unmatched url, redirect to /root
    $urlRouterProvider.otherwise("/transfers");

     $stateProvider
        .state('transfers', {
            url: '/transfers',
            templateUrl: 'transfers.html',
        })
        .state('about', {
            url: '/about',
            templateUrl: 'about.html'
        })
        .state('upload', {
            url: '/upload',
            templateUrl: 'upload.html'
        });
  }
})();

though I'm still unsure why yours doesn't work...
