WP_Textdomain_Registry::reset() method undefined call

Question

My WordPress site is broken, showing only 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
Stack trace:

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

Answer 1

This is a problem when updating to wordpress 6.1.

To fix this issue you need to update WPML to 4.5.12 and string translations to 3.2.3

--edit:

After downloading the two updated plug-ins, rename the two folders related to the plug-ins and install the updated version to solve the problem
