Solution to Favicon in Genesis
Favicons usually just go into the root folder of your site, and that is that, right?
So, I started googling around and found that, of all things, you have to put the favicon not only in your root folder, but also in your themes folder, and if you have a child theme, in there as well.
So, for Genesis, at least, they are not playing by the rules. Why is it that every freamework has different rules, and yet they are all playing with WordPress.
