Transparent header in all single post

Hi,

Thank you for the update.

Please add this in the functions.php file.

add_action( 'after_setup_theme', 'enfold_customization_product_switch' );
function enfold_customization_product_switch(){
	add_filter('avf_builder_elements', 'avf_builder_elements_mod');
}

function avf_builder_elements_mod($elements)
{
    $screen = get_current_screen();
    if( 'post' == $screen->id  )  {
        $counter = 0;
        foreach($elements as $element)
        {
        	if($element['id'] == 'header_transparency')  {
                $elements[$counter]['std'] = 'header_transparent';
            }

            $counter++;
        }
    }
	return $elements;
}

Best regards,
Ismael
