I get a blank windows after splashscreen (no framework7 css and js loaded, router not ok., only static text is displayed)
The index.html is loaded (i put “Test index.html” inside to be sure, but “Menu”/Css and other content is not displayed, + Router navigation don’t work

/www/index.html










/www/app.js

var routes = {
// Index (empty)
{
path: ‘/’,
componentUrl: ‘pages/index.html’
},

	// Plannings
	{
		path: '/plannings/',
		async: function(routeTo, routeFrom, resolve, reject) {   
	...

var app = new Framework7({
	root: '#app',
	routes: routes,
	statusbar: {
		enabled: true
	},
	touch: {
		disableContextMenu: false
	}
}
