Problem:
PHP Fatal error: Uncaught Error: Call to undefined method WP_Textdomain_Registry

Solution:

WP 6.1 introduces breaking changes that make it necessary to update WPML and String Translation before updating WordPress (see https://wpml.org/changelog/2022/10/wpml-4-5-12-updates-for-wordpress-6-1/).

Please update both WPML and String Translation. (If necessary, from the commercial tab of the Add New plugins page which takes you to the custom WPML installer, click Check for Updates to see the current versions.)
