Hello,
I am just wondering which files I need to edit in order to let me have 3 letter State ISO codes.
So far I have tried editing classes/State.php and admin/tabs/AdminStates.php
All I managed to do was give me the ability to type it in, but not to save it as something is validating it, and I am curious which file(s) it is.
If anyone has done this before let me know.
Regards,
Sean
