I do not recommend doing this because you will then have to log in to your SmugMug account from SmugMug’s homepage. But if you decide that you still would like to hide the SmugMug footer from your SmugMug website – here is how to do this.
Add a CSS content block to the ENTIRE SITE section of your website and then add this code to it:
CSS
/*Hiding SmugMug footer*/
.sm-user-ui .sm-page-powered-by {
display: none;
}
