Problem: The client is experiencing issues with updating custom fields on products using WPML during a large import process. The import stops after updating some products, with an error indicating a type mismatch in WooCommerce Multilingual plugin. Solution: We recommend trying the solution provided in the WPML forum: WPML forum thread. If the issue persists, we suggest migrating the site to a test server for further debugging without risking the live site. You can use the Cloudways WordPress Migrator plugin for this purpose. More details on migration can be found here: How to migrate WordPress to Cloudways.
If these steps do not resolve the issue, or if the solution seems outdated or irrelevant to your specific case, please open a new support ticket. We highly recommend checking related known issues at WPML Known Issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. For further assistance, you can contact us directly through the WPML support forum.
