I cloned a project from github over to my desktop. I used to work on it form my laptop.
However, on laptop heroku does not seem to work for this app eventhough i have i
When I had this issue it was because I created more than one remote app on heroku.
To remove an existing remote app from heroku use:
git remote rm heroku
then go back and use heroku create to start the process over using the correct app name heroku gives you.
