This thread is resolved. Here is a description of the problem and solution.
Problem:
The client is unable to log in to WordPress after updating to version 4.7 or higher. The error message indicates that some WPML components are not updated, specifically mentioning that 'sitepress-multilingual-cms' needs to be version 4.7.0.
Solution:
We recommend updating all WPML plugins to their latest versions. First, disable and delete the current WPML plugins, then download and install fresh copies from the 'My Account -> Downloads' section on our website. Ensure you also update your WordPress to the latest version. For detailed instructions on updating WPML, visit http://wpml.org/faq/install-wpml/.
Next, enable debugging to identify any specific errors. Modify your wp-config.php file by changing:
define('WP_DEBUG', false);
to
define('WP_DEBUG', true);
Also, add:
define('WP_DEBUG_LOG', true);
This will save error logs to a debug.log file in your /wp-content/ directory. For more on debugging WPML, visit https://wpml.org/documentation/support/debugging-wpml/.
Always ensure to back up your database before proceeding with these updates.
If this solution does not resolve your issue or seems outdated, please check for related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If problems persist, we highly recommend opening a new support ticket for further assistance.
