Bug update & String translation in checkout

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is unable to update WPML to version 4.7.1 even though it is registered, and this issue is causing a fatal error on the cart page after updating other plugins.
Solution:
If you're experiencing this issue, we recommend you follow these steps:
1. Take a complete backup of your site.
2. Deactivate all WPML plugins, including the WooCommerce Multilingual plugin.
3. Download the latest copies of WPML and WooCommerce Multilingual from https://wpml.org/account/downloads/.
4. Delete the WPML plugins (your settings and translations are saved in the database and will not be deleted.)
5. Upload the freshly downloaded WPML plugins by going to Plugins -> Add New -> Upload Plugin.
6. Activate the plugins.

This solution might be irrelevant if it's outdated or not applicable to your case. We highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.

alexandreB-46	Background of the issue: I am trying to update to the latest version of all WP components installed. The issue can be seen on this page: hidden link. After updating the plugins, I received a message indicating that the WPML update is incomplete. The message states that I am running updated versions of woocommerce-multilingual and wpml-string-translation, but sitepress-multilingual-cms is not updated to the required version 4.7.0. My WPML is registered, but I can't update WPML to 4.7.1, even manually, and it triggers a fatal error in the cart page: Uncaught Error: Call to undefined function WCMLTaxStringsicl_get_string_id() in /var/www/*****/wp-content/plugins/woocommerce-multilingual/classes/Tax/Strings/Hooks.php on line 26. Symptoms: After updating the plugins, I received a message indicating that the WPML update is incomplete. My WPML is registered, but I can't update WPML to 4.7.1, even manually, and it triggers a fatal error in the cart page: Uncaught Error: Call to undefined function WCMLTaxStringsicl_get_string_id() in /var/www/***/wp-content/plugins/woocommerce-multilingual/classes/Tax/Strings/Hooks.php on line 26. Questions:** Why can't I update WPML to version 4.7.1? How can I resolve the fatal error in the cart page?
