Adding Pages Removed Header

First of all, hello, and thank you for helping – whoever you are. ??

I am having a problem with this theme. I set up my header beautifully with a picture of me and a new background image. Then, I went to add the pages that I was going to need and after adding three pages (for a total of four with the sample page that was already there) and two child pages under one of them I went to check out how it looked and when I refreshed my site I was appalled to see that my header was gone. So, I went back and deleted pages one at a time to try to find the problem and when I had deleted all of them, including the example page (which I renamed)my header still hadn’t come back. I went to the theme options and looked and everything is still there – it shows the header image I selected and all of the other elements I had set up but nothing is showing. It went back to the header image I had replaced and will not go back to the way it was. What do I do?
