Git: nothing added to commit but untracked files present
For this question, you have two options
1. Add the untracked files to your git repository
2. Add the files to the .gitignore file If you want git to ignore them.
For adding the untracked files you could use :
git add Optimization/language/languageUpdate.php
git add email_test.php
And to ignore the files you need to add the following lines to your .gitignorefile:
/Optimization/language/languageUpdate.php
/email_test.php
These two options will allow the git pull to succeed.
