Warning: Division by Zero Error

Hey! I’ve been getting an error on the shop page of my site:

Warning : Division by zero in /home4/krystlejosea/public_html/wp-content/themes/pinnacle/lib/custom-woocommerce.php on line 315

echo '<div class="kt-cat-intrinsic" style="padding-bottom:'. ($cat_image[2]/$cat_image[1]) * 100 .'%;">';

http://krystlejosea.com/shop/

My page is supposed to be displaying the category images as normal but this error is showing for all the images. How can I fix this? I think it is a theme issue but I am not sure. Any help is greatly appreciated.

I’m using Pinnacle version 1.4.0 btw.
