Reply To: Custom 404 Page

I am trying to duplicate the default 404 page on a custom page. I want to disable the footer and use a different header. I found the image but I am having a problem with the image duplicating as a background. Can you advise how to do this.

Or

I see I can remove the Search and footer from the 404.php. Is it possible to load another header other than the default header that I created using the header builder in the 404.php file?
