I am trying to do a Route in AngularJS 1.6.6, but I don't realize why it's not working.
I have searched for every post here about this subject, but I didn't find the answer.
I am trying to run this on WAMP local server. So far, everything worked, except when I started using ngRoute.
It's not the same problem that I have found (like this angularjs 1.6.0 (latest now) routes not working) because I am not trying to click in a link to reach out the main.html, but so only to load this inside the index.html as a main content (the first content to be displayed).
app.js
angular.module('warmup', ['ngRoute'])
.config(function($locationProvider, $routeProvider){
    //$locationProvider.html5Mode(false).hashPrefix(''); => this is something that I tried...
    $routeProvider
    .when('/', {
        templateURL: 'views/main.html',
        controller: 'BoardController'
    })
    .otherwise({redirectTo: '/'});
});

The application doesn't display any error, and all of assets load ok. But I only see a blank page instead:

When I inspect the page, I see my <ng-view> only as a comment in the html. 
If I move the main.html content in place of <ng-view>, write the ng-controller="BoardController" inside of <div class="container"> (in index.html) and I comment the routes on app.js, everything works (that means there is no error in my Controller, I think):
