Problem: You are trying to do automatic translation for products on your site but encounter an OUT OF CREDIT message, despite having assigned credit to your site. Solution: If you're experiencing this issue, we recommend you first remove your domain from your account dashboard at this link: https://wpml.org/account/sites/. After removing the domain, generate a new site key for this domain. Next, navigate to WP > Plugins > Add New > Commercial Tab in your WordPress dashboard and replace the site key with the new one.
After completing these steps, if the problem persists, it might be due to an outdated solution or a different issue not covered here. 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 necessary, please open a new support ticket at WPML support forum for further assistance.
