Call to undefined method WP_Textdomain_Registry::reset()

Question

My Wordpress site is broken and only shows this error message:

Fatal error: Uncaught Error: Call to undefined method WP_Textdomain_Registry::reset() in /var/www/htdocs/wp-content/plugins/wpml-string-translation/classes/MO/Hooks/LanguageSwitch.php:139

I can only access the site after adding ".disabled" to the plugin folder (wpml-string-translation) name but this disables the plugin and the site needs it to work.

It is a problem that is occurring with the update to wordpress 6.1.

To fix it you need to update WPML to 4.5.12 and String Translation to 3.2.3

-- Edit:

After downloading the two updated plugins, rename the two folders related to the plugins and install the updated versions to solve the problem
