The client was unable to see cross-sell products in other languages on their WooCommerce site after updating WPML. The products were set up in the default language (English) and were not being copied to translated versions.

We recommend the following steps to resolve the issue: 1. Navigate to WPML → Settings → Custom Fields Translation. Click on Show system fields. Set <code>_upsell_ids</code> and <code>_crosssell_ids</code> to Copy or Copy once and then save. If already set, change it to translate and then back to copy. 2. Ensure that every product referenced as a cross-sell/upsell is translated and linked. Check that the translation is 100% complete using the pencil icon. Update the original product and its translations to trigger WPML synchronization. 3. Go to WooCommerce → WPML Multilingual & Multicurrency → Settings → Troubleshooting and run the following:<ul><li>Synchronize data into translations</li><li>Fix language connections</li><li>Delete obsolete custom fields from translations</li></ul> 4. Clear any caches (e.g., Redis, Memcached) and repeat the update step on the original product and its translations. 5. If the issue persists, test for plugin or theme conflicts. Disable all plugins except for WooCommerce and WPML, switch to a default theme like Twenty Twenty-five, and check if the issue resolves. If resolved, reactivate each item one by one to identify the conflict. If these steps do not resolve your issue, or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at <a href=\'https://wpml.org/known-issues/\'>https://wpml.org/known-issues/</a>, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If problems persist, please open a new support ticket at <a href=\'https://wpml.org/forums/forum/english-support/\'>WPML support forum</a>.
