I’d like to modify “header-4.php” a little bit – change the order of social icons etc. The file responsible for this header is located in: gillion/inc/headers/header-4.php
I edited this file and copied to child theme folder: gillion-child/inc/headers/header-4.php
Unfortunately WP doesn’t see modified file. Could you please help me to manage it as if you did here: https://support.shufflehound.com/forums/topic/blog-slider-editing/
I assume that I need some custom code to paste info functions.php in child theme, right?
It seems you are editing it in the right directory path in child theme.
Please make sure you are using Header layout 4 and try temporary removing whole code from the file gillion-child/inc/headers/header-4.php to test it is working or not.
