Because the problem was not clear i created new ionic app and i started to build it step by step testing in parallel with the Edge…i noticed that just added NavController and specially the below code
goToRegisterPage(event) :void
{
this.navController.push(RegisterPage);
}
the same error reappeared.
(i have import the core-js library to my index file)
What’s wrong? thank u in advance
