That code only works with the older version of Genesis. Every since Genesis 2.0 they removed that feature from the footer. Plus, if you were to add the code in manually somewhere in your footer, you would need to add an ID for it to link to. If you just add the link itself and you have no ID then it won’t work, so you’ll need to add an ID near the top of your site….SP has some docs on how to hook code in.
