This thread is resolved. Here is a description of the problem and solution.
Problem:
The client was encountering a critical error in the WooCommerce orders panel after updating to RC 5.4.0-rc.1. The error, 'Call to a member function get_title() on bool', occurred due to the WooCommerce Multilingual plugin not finding a specific shipping method, causing the function
WC_Shipping_Zones::get_shipping_method($shippingInstanceId)
to return false.
Solution:
We recommended the following steps:
1. Ensure you have a backup of your site.
2. Deactivate all plugins except for WPML and WooCommerce, and switch to a default WordPress theme to check if the issue persists.
3. If the problem continues, create a staging site and provide us with admin access for further investigation.
4. As a temporary workaround, modify the file
wp-content/plugins/woocommerce-multilingual/classes/OrderItems/Shipping/ShippingMethod.php
. After the line:
$shippingMethod = \WC_Shipping_Zones::get_shipping_method($shippingInstanceId);
Add the following code:
if ($shippingMethod === false){<br /> return;<br />}This change prevents the error by stopping the function execution if the shipping method is not found.
