Error-404 No header
There is no option to provide a header for the 404 page. I am using the custom 404 page (Muffin Options > Getting Started > Advanced) and the unique page I chose is showing the builder content w/ sidebar but no header. I didn't check footer because I have built that in via the page's muffin builder and it shows as desired. I would like it to match the rest of my site.
I should add that the permalink of the actual 404 page does show the header.

Copy 404.php from the betheme directory to your child theme directory.
Edit the copy of 404.php:
1) Add the line <?php get_header();?> to the start of the file (directly below the line <?php wp_head();?>).
2) Add the line <?php get_footer(); ?> at the end of the file (directly above the line <!-- wp_footer() -->).
