Background of the issue:
I am editing some products and when I try to update them, I am getting a critical error from the WooCommerce Multilingual & Multicurrency plugin. This happened immediately after I updated the plugin to the latest version 5.5.0. I had to rollback to a previous version in order to edit the products.

Symptoms:
A critical error occurs when updating products after updating the WooCommerce Multilingual & Multicurrency plugin to version 5.5.0.

Questions:
Why does the critical error occur after updating to version 5.5.0?
How can I resolve the critical error without rolling back the plugin?

Hello,

Welcome to the WPML support forum. I will do my best to help you resolve the issue.

This issue may be related to a compatibility problem, possibly connected to the following errata or ticket. Please try the workaround suggested there after a full site backup:

https://wpml.org/errata/woocommerce-multilingual-fatal-error-when-saving-a-translation-in-the-native-wp-editor/

https://wpml.org/forums/topic/fatal-error-uncaught-typeerror-illegal-offset-type/

If the problem remains, do you have a staging or development site where we can investigate this further? It will help us troubleshoot the bug safely without affecting your live site.

Just to confirm, have you made any recent changes to the site apart from upgrading to the latest version of WooCommerce Multilingual?

Thanks!
