cannot push to github: everything up-to-date

Question

On github, I forked an old version of another project. I made some changes and am trying to push them onto my fork on github. I commited the changes locally, then tried git

Answer 1

git commit 

Will show you what files are on your local machine, uncomment what you want to upload and

git push origin master

Because git add * did not work for me (even if it didn't returned errors).
