Problem: After migrating a site from a staging environment to production, the Advanced Translation Editor (ATE) cloud was rejecting all translation jobs with an HTTP 426 error, indicating a URL change. The client attempted various troubleshooting steps, including reactivating WPML plugins and confirming site key registration, but the issue persisted. Solution: We recommended the client to re-save the original pages in the default language (DE) to refresh the database entries. This action allowed the ATE to recognize the correct production URL and accept translation jobs. The client confirmed that after re-saving the affected pages and updating the translations, the issue was resolved.
If this solution does not apply to your case, or if it seems outdated, please check the related known issues and confirm that you have installed the latest versions of themes and plugins. If the problem persists, we highly recommend opening a new support ticket at WPML support forum.
