Problem: The client is attempting to upgrade to version 5.3.2 of WC Multilingual & Multicurrency but encounters an 'Update failed: undefined' error. Solution: 1. We recommend following the steps provided by our colleague in an existing support ticket, which can be found here: https://wpml.org/forums/topic/update-failed-undefined-12/#post-14874347. 2. If the issue persists, create a full website backup. Then, disable and uninstall the plugin that is causing the issue. After that, manually download the plugin from the following link: https://wpml.org/download/woocommerce-multilingual-multicurrency/?section=changelog. Next, navigate to your site's backend > Plugins > Add new > Upload, select the zip file you downloaded, and install it manually. This should resolve the error as you are not updating the plugin but installing the new version manually.
