Problem:
The client is experiencing issues with their WPML installation in production on Pantheon. They are unable to register their site due to a mismatch in the 'site_key' between their wp-config.php and the database, and cannot access the 'commercial' tab to register the site. They also cannot allocate credits on wpml.org as the PROD site is not active.
Solution:
We recommend the following steps to resolve the issue:
1. Visit https://wpml.org/account/sites and remove any old versions of the website from the list.
2. Add the production website URL again and copy the newly generated key.
3. Update the key in your wp-config.php file to match the newly generated key.

This process should help in correctly registering your site in production, allowing you to assign credits and activate PAYG translation services.

If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
