I am trying to set up a map of tweets related to a particular hashtag in Crowdmap Classic. I did the whole procedure showed in this link, up to the creation of the twitter application. But, when I have to "Test OAuth" and I click the button, this is what happens:
I tried going on both in Heroku and in Crowdmap classic and it did not work. I suspect that the reason is the twitter application and the access denial.
Could you please help me with that? Is there something wrong with my twitter account?
Thank you very much.
