Problem: You are trying to use pre-purchased automatic translation credits with WPML, but the plugin does not recognize these credits and prompts you to purchase more. Despite de-registering and re-registering with your key, the issue persists. Solution: First, ensure that the credits are correctly assigned to your current WPML account. If you see discrepancies, such as credits appearing in one account but not in another, you might need to transfer these credits back to your main WPML.org account. Follow these steps: 1. Visit https://wpml.org/account/sites/ and remove the current site key. 2. Generate a new site key. 3. Go to your website's backend, navigate to Plugins > Add new > Commercial, and unregister WPML from the old key. 4. Re-register WPML using the new key. 5. Re-add the credits to your site by following the steps provided here: https://wpml.org/documentation/automatic-translation/how-to-assign-automatic-translation-credits-to-your-sites/
If this solution does not resolve your issue or seems irrelevant due to changes in WPML versions or your specific setup, we recommend opening a new support ticket. Also, check 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. For further assistance, please contact us through the WPML support forum.
