I've added a few details at the top to explain how I got where I am.
I've created a Rails 3.2 application and I'm pushing it to Heroku. I've pushed several sites to Heroku so I've done this a fair number of times. However, I've never seen this.
I started out with my normal "heroku create" command, then "git push heroku master". When I ran that it returned with the message "No such app as..."
Based on what I saw on Stack Overflow here Pushing app to Heroku problem I then entered "git remote -v", saw two heroku items, entered "git remote rm heroku" to remove these items. I re-ran the "heroku create", "git push heroku master" and the site did push to Heroku, but Heroku thinks it's a PHP site.
There isn't a single line of PHP code in my entire app. In fact the string "PHP" don't exist anywhere.
What did I do wrong and how can I fix it?
Thanks in advance.
