“invalid argument” error in cart page

Hi there,

I am receiving this message in the cart page when I add the what’s app chat to order button on the cart page:

Warning: Invalid argument supplied for foreach() in /home/customer/www/garimpohome.com/public_html/wp-content/plugins/oneclick-whatsapp-order/includes/buttons/wa-order-cart-page.php on line 307

How to fix this?

Thanks,

Silvio
