Recipe Card Plugin warning

Hello, I have got an odd warning in my recipe card. It says: Warning: Invalid argument supplied for foreach() in /home/jynhar/redhillrecipes.com/wp-content/plugins/recipe-card/yumprint-recipe.php on line 954

Here is a link to the page with the problem: https://www.redhillrecipes.com/a-healthy-carrot-cake-masquerades-as-decadent/

What can I do to fix this?

Thanks!
