I had the same issue but it's solved now:

1. change

getMessages in chat.service.ts to be like this
getMessages():FirebaseListObservable<ChatMessage[]>{ return this.db.list('Messages', { query :{ limitToLast:25, orderByKey:true } }); }
2. in chat.service.ts and app.module.ts you have to change
import {AngularFireDatabaseModule} from 'angularfire2/database'; //to be like thisimport {AngularFireDatabaseModule} from 'angularfire2/database-deprecated';

Hi @anonnoisy, @anthony-coplo, @JBuckGuy, @sameeranihathe
Look at this #10 (comment)

AngularFire has moved, we're now @angular/fire
you have to use '@angular/fire/database-deprecated' in place of 'angularfire2/database-deprecated' or 'angularfire2/database'
This worked for me.
