If yo have just installed git, or are working with a new user with git, then you may get a message like:
*** Please tell me who you are. Run git config --global user.email "you@example.com" git config --global user.name "Your Name" to set your account's default identity. Omit --global to set the identity only in this repository. fatal: unable to auto-detect email address (got 'www-data@LiveWorld.(none)')
In this case you will need to configure git - just issue the two command suggested with your details filled in.
As far as I know you can fill in anything you want as the information is for informational purposes only. But useful for debugging.
