Header is Missing (Inspiro Lite)

(Under Construction mode is currently enabled on the site so the link won’t be visible.)

Hi! I’m building a site using Inspiro + Elementor. At some point through the process, the Inspiro header (which I had already customised etc) disappeared. I’ve tried everything I could think of or read about to get it back, but it still isn’t showing.

Could somebody please help me?
