Problem:
The client was unable to translate a WooCommerce product due to a fatal error related to

array_filter()

in the WooCommerce Multilingual plugin.

Solution:
1. We recommended updating the WooCommerce Multilingual & Multicurrency plugin to version 5.3.4 to ensure the client is working with the latest bug fixes and improvements. Update instructions can be found at http://wpml.org/faq/install-wpml/.
2. If the issue persists after the update, we provided a workaround from our errata page: https://wpml.org/errata/advanced-custom-fields-php-fatal-error-uncaught-typeerror-array_filter-argument-1-array-must-be-of-type-array/. This workaround helped to resolve the issue.
