Fatal error undefined list_products_html() WP 5.8 Woo 5.5.2

  • I actually wanted to update WooCommerce to version 5.5.2 on my testing environment but accidentally hit the update WordPress to 5.8 button.
    After updating I got a fatal error when going to the widgets management page of WordPress. After updating YITH WooCommerse Compare to version 2.5.3 I still got the same fatal error.
    What can I do to fix this?

    Fatal error: Uncaught Error: Call to undefined method YITH_Woocompare_Admin::list_products_html() in \website-root\wp-content\plugins\yith-woocommerce-compare\widgets\class.yith-woocompare-widget.php:47 Stack trace: #0 \website-root\wp-includes\class-wp-widget.php(393): YITH_Woocompare_Widget->widget(Array, Array) #1 \website-root\wp-includes\widgets.php(1977): WP_Widget->display_callback(Array, Array) #2 \website-root\wp-includes\rest-api\endpoints\class-wp-rest-widgets-controller.php(630): wp_render_widget('yith-woocompare...', 'shop-sidebar') #3 \website-root\wp-includes\rest-api\endpoints\class-wp-rest-widgets-controller.php(122): WP_REST_Widgets_Controller->prepare_item_for_response(Array, Object(WP_REST_Request)) #4 \website-root\wp-includes\rest-api\class-wp-rest-server.php(1140): WP_REST_Wi in \website-root\wp-content\plugins\yith-woocommerce-compare\widgets\class.yith-woocompare-widget.php on line 47

    Hi there,
    please download the file you find at this link and move it to the following path:
    wp-content\plugins\yith_woocommerce-compare\widgets

    Let me know if the problem persists.

    Suddenly the problem seems to be gone so I haven’t applied your file.
    Maybe it has something to do with another (faulty) plugin that wasn’t updated or deactivated yet.

    Hi there,
    great, we remain at your disposal for the future ??

    I am facing the same issue and I have wordpress 5.8 and woo 5.5.2. The problem seems to gone when I deactivate and activate plugin but it removes the widget for compare. When I add the widget back the error again comes back. I am using elementor pro. Pl fix this with an update asap.

    I got a error after updating the YITH plugin.

    WordPress caught an error with one of your plugins, YITH WooCommerce Compare.

    Kindly help me to resolve the issue.

    I’ve got the same error after updating:

    PHP Fatal error: Uncaught Error: Call to undefined method YITH_Woocompare_Admin::list_products_html()

    In the frontend the widget shows up as expected but under Appearence / Widgets in the dashboard it throws the error above.

    I tried to dig further into the issue but I couldn’t figure it out.

    Any help would be appreceated!

    I got an error after updating the YITH plugin.

    Kindly give support, I can’t open the widget tab due to this error.
