Ahhh, I was adding a function of the template-tags.php to my child theme functions.php but I forgot I’d already added another function that applied to the tagline, so I just edited that function with this function… http://www.kirstencassidy.com/allow-html-code-in-wordpress-tagline/
It should work, but if not you can always just add your site title and tagline using GP Hooks which gives you complete freedom over what to do with the code 🙂
