Editor X Header

Hoping if I describe the symptoms someone might be able to diagnose…

I’ve an editor x site and the header was displaying fine across viewports. But, now there is a space on tablet and mobile either side (left and right) of the container with the logo and menu in (i.e. I can’t get the header to display full width).

  • No padding or margins set.

  • I’ve rebuilt to no avail.

  • I’ve removed all overrides.

  • I’ve unpicked all the elements on all the layers related to it and can’t find anything out of line.

Any suggestions?
