Could anyone give me a hint why I have to override the Method Meteor.navigateTo? I Can't find a discription of this method. Seems to be a method of the package mini-pages.
// override with mini-pages navigate method
Meteor.navigateTo = function (path) {
Router.go(path);
}
I'm not sure you'll receive an answer for this; mini-pages was superseded by iron-router which has been superseded by Flow-Router https://github.com/kadirahq/flow-router.
I'd suggest you move over to Flow-Router as per the Meteor guide.
