Problem: The client is experiencing a WordPress critical error when trying to add new products using WooCommerce Multilingual & Multicurrency. The error message indicates an issue with calling a function on a non-existent object in the WooCommerce Multilingual plugin. Solution: We were unable to replicate the issue directly. However, we recommend checking if the problem might be related to a known issue with WPML that affects admin access to translation management. You can find more details and potential workarounds here: WPML Errata. If this solution does not resolve your issue or seems unrelated, it might be outdated or not applicable to your specific case. 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. If the problem persists, please open a new support ticket.
