Error while adding new feed

Hello,

Installed and activated plugin. Trying to add a new feed we get the following error, and nothing else loads in the page.

Fatal error: Uncaught Error: Call to undefined function wc_get_attribute_taxonomy_labels() in /home/simplyg0/public_html/wp-content/plugins/webappick-product-feed-for-woocommerce/includes/classes/class-woo-feed-products.php:1708 Stack trace: #0 /home/simplyg0/public_html/wp-content/plugins/webappick-product-feed-for-woocommerce/includes/classes/class-woo-feed-products.php(1877): Woo_Feed_Products->getAllAttributes() #1 /home/simplyg0/public_html/wp-content/plugins/webappick-product-feed-for-woocommerce/admin/partials/woo-feed-admin-display.php(18): Woo_Feed_Products->load_attributes() #2 /home/simplyg0/public_html/wp-content/plugins/webappick-product-feed-for-woocommerce/woo-feed.php(864): require(‘/home/simplyg0/…’) #3 /home/simplyg0/public_html/wp-includes/class-wp-hook.php(286): woo_feed_generate_feed(”) #4 /home/simplyg0/public_html/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(”, Array) #5 /home/simplyg0/public_html/wp-includes/plugin.php(465): WP_Hook->do_action(Array) #6 /home/simplyg0/public_html/ in /home/simplyg0/public_html/wp-content/plugins/webappick-product-feed-for-woocommerce/includes/classes/class-woo-feed-products.php on line 1708
