I recently answered the same question on official Sparkling support forum and I hope that you don’t mind if I will point you to that discussion: http://colorlib.com/wp/forums/topic/missing-tagline/#post-6340
I beg your pardon, Silkalns, but just to clarify … the topic you linked to is not the same question as ‘ceomkg’ raised. His issue is not about the Tagline (description) not showing, but about neither the Site Title nor the Tagline showing, ie. none of the Header Text.
If a logo (header image) is uploaded then the site title and tagline do not display at all, even if “Show header text with your image” is enabled in the Header submenu and even if “Display Header Text” is enabled in Customize > Site Title & Tagline.
The use of a header image excludes the use of header text due to the logic in header.php.
Oh, and about the missing tagline issue at http://colorlib.com/wp/forums/topic/missing-tagline/#post-6337, it really isn’t too difficult to fit a tagline in underneath the site title. It just takes a 14px font instead of a 16px. I’d post about it on your site over there, but I don’t have an account.
Cheers,
Terry
P.S. Very nice theme by the way!
