I tried to make a settings page but when I click on settings button to navigate to that page, the following above error is appearing on console. Can anyone please help me to resolve this issue.

Answer 1

Your error is linked to the NgxToastr lib, the config is missing. Did you import the module in your app.module.ts?

@NgModule({
  imports: [
    ToastrModule.forRoot() // ToastrModule added
  ] ...
