Getting error message “This product cannot be purchased.”

Hi, after adding textarea and file upload (image/*) I get an error when trying to add products when using woocommerce woth the woo plugin Product Table (https://barn2.co.uk/wordpress-plugins/woocommerce-product-table/), https://gjohnsenbakeri.no/bestilling/ (Tab: Kaker) but on regular product view; https://gjohnsenbakeri.no/produkt/lukket-flote/ it works. How can I get it to also work when in product table view?
