Problem: The client is unable to upgrade WPML plugins through the website as the license key is not accepted. Solution: If you're experiencing this issue, it usually occurs when WPML is registered with an expired license key. We recommend following these steps to resolve the problem: 1. Log in to your WPML.org account and go to the Sites page. 2. Delete the existing site key by pressing the little trash icon. 3. Log in to your site and navigate to the Dashboard >> Plugins >> Add new >> Commercial tab and click the Unregister WPML from this site link. 4. Then click the Register WPML link. 5. Click the Get a key for this site link. 6. It will generate a new key for your site. 7. Copy the new key, paste it into the input box, and press the Register button to see if this resolves the issue.
Please ensure to backup your database and website before proceeding with these steps.
