Add a class to the Body Class

So you need to add a class to the body classes to get stuff to work right. Here is a way to do it. Also, change woocommerce-page to something useful to you.

function mlp_add_a_filter($classes){
	$classes[]="woocommerce-page";
	return $classes;
	}

add_filter('body_class','mlp_add_a_filter');

If you know you are using PHP 5.3 or above, here is a quicker way

add_filter('body_class',function($classes){$classes[]="woocommerce-page";return $classes;});
