Shapely: Theme Header (header.php) Missing

Hi, so I went to my website this morning only to see it not looking the same, I had just updated all my plugins and thought maybe something from there had messed with it but could not see anything.

I went through the editor and each theme files to notice in my Theme Header it’s empty which is odd because I clearly remember seeing stuff there. I have no idea how to get all the coding back.

hi there

I don’t know what happened in your files but you can update the theme and a new file will replace your blank file,
you can also download the theme from WordPress repository and manually add content from the header.php into your theme.
