Code in Header

this worked for me: <?php echo do_shortcode(“[shortcode]”); ?>

Found here: https://css-tricks.com/snippets/wordpress/shortcode-in-a-template/

Hi there,

Yes, you can either use the code Leslie suggested or use the function that comes with the plugin.

<?php if(function_exists('mc4wp_form')) { mc4wp_form(); } ?>

Or..

<?php echo do_shortcode('[mc4wp_form]'); ?>

Hope that helps!
