Hi pbjwordpress,
My apologies, there is a disconnect as that custom.css option is intended for the Pro version’s update system, where it is paired with an auto-backup & auto-restore of that file. Unfortunately that’s not part of the Lite version and the custom.css shouldn’t be an setting there, sorry about that!
To add a custom stylesheet, I’d suggest using this code:
function my_custom_shiftnav_style() {
$stylesheet_url = get_stylesheet_directory_uri() . '/css/shiftnav-custom.css'; // Make sure this matches your stylesheet's URL
wp_enqueue_style( 'custom-shiftnav-css', $stylesheet_url, array( 'shiftnav' ), '1.0' );
}
add_action( 'wp_enqueue_scripts', 'my_custom_shiftnav_style' );
and placing a stylesheet called shiftnav-custom.css
in your child theme’s css/
directory.
That way the file won’t get deleted when you update.
Then you can just disable the ShiftNav skin in the settings.
Hope that helps and sorry for the trouble!
