Solved Header Gone While In Editor

This is intended. Due to the limitation of our new feature: Custom Header & Navigation Styling, we have to hide the header in the Visual Builder. We do believe that this won't cause any harm to your site building process.

You can add this CSS:

html.et_fb_desktop_mode #main-header, html.et_fb_preview_active #main-header,
html.et_fb_desktop_mode #top-header, html.et_fb_preview_active #top-header {
display: block!important;
}
