Woocommerce error when items are in cart

I’ve installed WooCommerce and WooCommerce Customiser at https://ciderpressreview.com/shop. When I load any products to the cart, i get the following error messages:

Warning: array_intersect() [function.array-intersect]: Argument #1 is not an array in /home/ciderpre/public_html/admin/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-shipping-method.php on line 180

Warning: in_array() expects parameter 2 to be array, null given in /home/ciderpre/public_html/admin/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-shipping-method.php on line 190

I had the same problem with the Woocommerce Product Archive Customiser plugin so changed to Woocommerce Custmizer plugin to achieve the same results. Unfortunately, the same problem persists, focused in abstract-wc-shipping-method.php.

Please advise if there is a fix available.

Thanks,

Caron
