All good. I followed your instructions from the above link posted by Romanko.
I just needed to make sure that the php before that section was “closed” to avoid an error by popping a ?> at the end, then pasting the logo bit… hope that maybe helps Romanko?
I am using a child theme with a modified header.php, too (been a while since I set it up and many too-short nights with a baby now for me to remember exactly why), but I have the same issue. My Header has disappeared.
