Hi, I'm setting up a bethemed website with a blog involved. when clicking on the blog page, I see a header image. everything is fine. but when clicking on a single post, the header image is empty. It appears black. How can I fill it? Best would be a revolution slider that appears dependent on the blog categories. But first priority would be to get a header image at all. What do I have to do? And if it's not possible, how can I hide the empty header image?
Thanks in advance and best regards
