我对Courspress和Woocommerce有问题。当我检查付费课程并添加woocommerce价格时，在商店页面和购物车上会出现致命错误。另外，我在wp后端看不到产品。
致命错误：
Fatal error: Uncaught Error: Call to a member function get_image() on boolean in /home/.../public_html/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-product.php:1828 Stack trace: #0 /home/.../public_html/wp-content/plugins/woocommerce/templates/cart/cart.php(64): WC_Product->get_image() #1 /home/.../public_html/wp-content/plugins/woocommerce/includes/wc-core-functions.php(208): include('/home/klient.dh...') #2 /home/.../public_html/wp-content/plugins/woocommerce/includes/shortcodes/class-wc-shortcode-cart.php(93): wc_get_template('cart/cart.php') #3 /home/.../public_html/wp-content/plugins/woocommerce/includes/class-wc-shortcodes.php(72): WC_Shortcode_Cart::output(Array) #4 /home/.../public_html/wp-content/plugins/woocommerce/includes/class-wc-shortcodes.php( in /home/.../public_html/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-product.php on line 1828
如何解决此问题？感谢您的帮助。
