Problem:
The client is experiencing an error in the WordPress backend stating that the WPML site key defined in the wp-config.php file is invalid, despite having checked and replaced the key.
Solution:
We have verified that the site keys created are not connected to the client's site and that the domains are not blocked by our firewall. This issue is recognized as a common problem with Pantheon setups. We recommend following the workaround provided by another user in the WPML forum: https://wpml.org/forums/topic/unable-to-register-live-site-key-on-site-hosted-with-pantheon/
Additionally, Pantheon is aware of this issue and is currently tracking it here: https://github.com/pantheon-systems/documentation/issues/9691
