title: Unable to pull change from github with Intellij Idea
body: <p>I would like to pull updates that a friends just pushed a week ago on github with intellij Idea. I open the project on my computer, checkout on the correct branch , went to <i>VCS ->git -> pull</i> , choose the correct branch , but nothing appended. </p>
  
  <p>Thus, I decided to go on github, to verify if those changes where applied on the repository, and yes, the repository  is up to date in github but i'm not able to pull changes. </p>
  
  <p>I also tried to clone the project and recreate a new project on Intellij Idea but it make no changes... </p>
  
  <p>Could somebody explain me how can i fix my problem, and get all changes made to the project ? </p>
