Problem: If you're experiencing issues with WooCommerce endpoints showing a 404 error on your multilingual site, particularly when switching languages, and it temporarily resolves by flushing permalinks but reoccurs, this might be relevant to you. Solution: We recommend updating your WPML Multilingual & Multicurrency for WooCommerce to version 5.5.4 once it is released, as it includes a fix for this issue. Ensure you always have the latest version installed. If this solution becomes outdated or does not resolve your specific case, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If the problem persists, we highly recommend opening a new support ticket at WPML support forum for further assistance.
