I get this error at the top of my screen and have no idea how to get it to go away.

Liquid error (layout/theme line 42): internal

I also have this error since updating to Dawn version 15.0.2.
I checked and on line 42, it's: {{ content_for_header }}

Are you also using Dawn?
The header shows just fine, just showing a block with the error at the top of the announcements. For now, I've rolled back to previous Dawn version. (Dawn 15.0.1). Does anybody know how to fix this issue so I can update to the latest version?

 All stores are experiencing this problem. Hope it should be fixed in the next few minutes.
