Warning adding products to

I am getting the following error when adding a product to the cart that has been set up with a coupon:

Warning: count(): Parameter must be an array or an object that implements Countable in /wp-content/plugins/wt-smart-coupons-for-woocommerce/admin/exclude-product/class-wt-exclude-product-for-coupon.php on line 108

Here is line 108 of the source code:
if( ! count( $this->get_disabled_product() ) > 0 ) return $valid;

It looks like the $this->get_disabled_product() is not an array by default and so the count() function does not work.

If I change the code to:
if( is_null( $this->get_disabled_product() ) ) return $valid;

then I do not get the error. However, I haven’t taken the time to go through all of the code to see what this might cause to break elsewhere.

The coupon is set up so that if you add 4 or more to the cart the code is automatically added to take 10% off the purchase. to get the warning please add 4 of the item in the link to the shopping cart. The warnings will show after the item is added to the cart as well as on the cart page itself.
