Ionic angular translate not working

Question

Im using ionic 2 and went through this document:

http://ionicframework.com/docs/resources/ng2-translate/

I made all the changes needed for translation to work. However, when I write this in an html file:

{{ 'HELLO' | translate }}

In the page I see

HELLO

This, even thought I have a file at /assets/i18n/en.json which contains:

{
    "HELLO": "Hello there"
}

In app.ts I added these imports:

import { TranslateModule, TranslateLoader } from '@ngx-translate/core';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';
import { Http } from '@angular/http';

And then after the imports I have this:

export function createTranslateLoader(http: Http) {
    return new TranslateHttpLoader(http, './assets/i18n/', '.json');
}

And also this in @NgModule->import's array:

TranslateModule.forRoot({
  loader: {
    provide: TranslateLoader,
    useFactory: (createTranslateLoader),
    deps: [Http]
  }
})

What I realized is that my app had since before this import:

import { HttpModule } from '@angular/http';

Im not sure why I imported that but if I remove it then the app breaks in other places. Is that the problem? Importing angular/http twice with two different names? Tried to only use the original one, but in the export function it doesn't like the argument

http: HttpModule

insead of the one in the documentation

http: Http

Can I see if the en.json has been loaded? Or what is the problem here?

You can see en.json using Inspector Web (F12). Do you use these methods somewhere in your code source?

this.translate.setDefaultLang('en');
this.translate.use('en');

In the view, you see only 'HELLO' because (I think so) you did not configure the language to use.
