Hi
I just updated to latest version 3.1.7, but now when I try to view an order page (like post.php?post=10206&action=edit) I get following error:
Fatal error: Uncaught Error: Call to a member function is_type() on bool
in /home/my_site/public_html/wp-content/plugins/cost-of-goods-for-woocommerce/includes/class-alg-wc-cog-products-add-stock.php on line 67
Please fix asap, now the plugin breaks the core functionality of my WooCommerce.
