Problem:
The client needed to change the WPML plugin key from a development key to a production key before transferring their website to a production domain.
Solution:
1. We instructed the client to create a new production key by visiting https://wpml.org/account/sites/.
2. After the migration to the production domain, the client should go to their site's backend, navigate to Plugins > Add New > Commercial, unregister WPML using the old key, and then re-register WPML with the new production key.

If this solution does not apply to your situation because it might be outdated or not relevant to your case, we recommend opening a new support ticket. We also 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. If further assistance is needed, please contact us in the WPML support forum.
