I attempted adding the following code at various locations in the child theme functions.php with no effect on the nav bar position…
add_action( ‘after_setup_theme’, ‘child_theme_setup’, 11 );
function child_theme_setup() {
remove_action( “omega_before_header”, ‘omega_get_primary_menu’ );
add_action( “omega_after_header”, ‘omega_get_primary_menu’ );
}
