Problem: The client is experiencing an issue where the inventory quantity on the English version of a WooCommerce site is not synchronized with the Greek version. All Greek products incorrectly show only 1 item in inventory, despite attempts to synchronize product taxonomies. Solution: 1. Navigate to WPML -> Settings -> Custom fields and click on Show System Fields. Search for 'stock' to check if it is set as 'copy'. 2. Go to WooCommerce -> WooCommerce Multilingual and click on the Status tab. At the bottom of the page, click on the 'troubleshooting' link and run through the options on this page. Ensure you have a full backup of your site before proceeding. 3. Update your WPML plugin and add-ons to the latest version, 4.8, to ensure you have the latest bug fixes and improvements. You can find the latest versions under My Account -> Downloads. Remember to backup your database before updating. 4. After updating, check if the inventory issue persists. If it does, try disabling all plugins except WPML, WooCommerce Multilingual & Multicurrency, and WooCommerce to see if the problem still occurs.
If these steps do not resolve your issue or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket.
