The Opencart extension Record Admin user name for Order status change is designed to record admin users who modified the order status. The order status is changed from the Order information page on the backend.
This is where the recording of the admin user name is done.

Once recorded you can view the data on the same page in the order history loaded.
No core files are changed.
