Functions.php not working in Child Theme

Hi,

I’ve been trying to add some php supplied from your documentation (and elsewhere) to the child theme’s functions.php via WP > Appearance > Theme Editor, but I keep getting a “Something went wrong” error message from WordPress.

This has happened with the following php:

Add search shortcode
add_shortcode(‘avia_search’, ‘get_search_form’);

Adding header widget area
add_action( ‘ava_after_main_menu’, ‘enfold_customization_header_widget_area’ );
function enfold_customization_header_widget_area() {
dynamic_sidebar( ‘header’ );
}

And adding a LinkedIn insight tag to the global footer.

Thanks,

Val
