After pushing updated version of my wordpress blog to OpenShift git repository, I have got “CARTRIDGE_VERSION_2: line 1: 2: command not found” error. You could see this error if you are pushing your changes in Drupal, WordPress, Rails, Spring, Django, Reveal.js, CakePHP, or Dancer applications.
git clone https://github.com/openshift/wordpress-example.git
Then copy and replace .openshift folder in your git repository with early downloaded.
Now you can commit this changes to repository.
git add . -A git commit -a -m "deploy fixed" git push
