Why does it always happen to me?
This happens after my application verify for user user login and redirect user to the authentication page:
https://w
The issue resolved after I updated the 'appID' and 'secret' and then pushed the change back to heroku (i.e. - 'git push heroku master')
The key is not to forget to push the changes back to heroku master. Very easy to overlook if you're use to testing on localhost.
Hope this helps.
