My website's header image has mysteriously vanished. No previous problems, no new updates or plug-ins. Tried de-installing all plugins, deleting cache, restarting, etc.
Now I can't even figure out how I uploaded it in the first place - there doesn't seem to be a place to add one either in Customize Theme or in Appearances / Settings.
The image is still in the media file, just can't see how to add it back to the header.
