I typed 0 in header area size. This is my big mistake.
The header doesn’t exist anywhere.
I can’t undo. Because I already saved it.
The header cannot be seen on the layer panel. Only pages(페이지) and footers(바닥글) exist.
Please help me anybody.
Hi @iamseulee ,
As you have set it to 0, and the editor seems not able to find it back.
Please restore a saved version of your site to get this resolved in a short time.

This is the solution I wanted. I didn’t know where the website history was. Thanks to you, my problem has been solved.
