I am new to WP and I am wondering if there is a way to undo changes to WordPress done via the accompanying PHP, JS, CSS files etc . I know you can undo changes directly within the Dashboard but I am trying to go beyond that. My PHP, JS knowledge etc is very limited at this time but at least I can make changes to the style.css file using Dreamweaver. Only problem now is that I have to save in order to see the changes and I get stuck if it doesn't work. Just wondering if there is a quick undo button somewhere that can be used once WP is transferred into another environment.
Thanks in advance
