For my version of the theme, I removed the title and tagline from appearing anywhere on the website, thus leaving the image header as the thing that says the site name.
Unfortunately, clicking on the header doesn’t link back to the home page. How can I get this to work?
You can either achieve this by selecting the header option “Header Logo Only” and setting the logo as shown in the first attached screenshot
Or disable the header as shown in the second attached screenshot and then set header image and use the attached small plugin specially developed for you that contains some custom code to make it link to the home page of site.
