Problem: The client is trying to return some translation credits to their main account but receives an error message indicating that credits cannot be withdrawn to wpml.org. Solution: We explained that when a site key is created, we provide 2,000 free credits per site. These credits are assigned specifically to that site and are not transferable between sites or back to the main account. Therefore, it is not possible to move them back to the main account.
If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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. If further assistance is needed, please open a new support ticket at WPML support forum.
