Templates not loading in angularJS and Ionic

I set up a basic ionic app with av few views and controllers. When I load the startpage I ALWAYS end up in $urlRouterProvider.otherwise('views/error.html'); line. And no templates gets loaded either.. even for the error.html.

I have no idea why. I get no js errors in the console or anything. Any ideas?

This is my code:

the html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <title></title>

    <link href="lib/ionic/css/ionic.css" rel="stylesheet">
    <link href="css/style.css" rel="stylesheet">

    <!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above
    <link href="css/ionic.app.css" rel="stylesheet">
    -->

    <!-- ionic/angularjs js -->
    <script src="lib/ionic/js/ionic.bundle.js"></script>

    <!-- cordova script (this will be a 404 during development) -->
    <script src="cordova.js"></script>

    <!-- your app's js -->
    <script src="js/app.js"></script>
    <script src="js/controllers/LoginController.js"></script>
    <script src="js/controllers/MainMenuController.js"></script>
    <script src="js/controllers/SettingsController.js"></script>
  </head>
  <body ng-app="iou">
    <ion-nav-view></ion-nav-view>
  </body>
</html>

the javascript

var app = angular.module('iou', ['ionic'])

.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
    // for form inputs)
    if(window.cordova && window.cordova.plugins.Keyboard) {
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
    }
    if(window.StatusBar) {
      StatusBar.styleDefault();
    }
  });
});

app.config(function($stateProvider, $urlRouterProvider) {

    $stateProvider.state('index', {
        url: '/',
        templateUrl: 'views/login.html',
        controller: 'LoginController'
    });

    $stateProvider.state('mainmenu', {
        url: '/mainmenu',
        templateUrl: 'views/mainmenu.html',
        controller: 'MainMenuController'
    });

    $stateProvider.state('settings', {
        url: '/settings',
        templateUrl: 'views/settings.html',
        controller: 'SettingsController'
    });

    $urlRouterProvider.otherwise('views/error.html'); // I always end up here
});

errors.html is in your views folder and has some markup to render? $urlRouteProvider.otherwise('directory/file.html') will always load first when your app starts up.

So the solution for me was to change:

$urlRouterProvider.otherwise('views/error.html');

to:

$urlRouterProvider.otherwise('/');
