Problem: After migrating a site from a temporary Cloudways staging URL to a final domain, WPML is not recognizing the sitekey, and all translation jobs are failing. Errors include 'AMS API returned false' and 'HTTP 426: WPML has detected a change in your site's URL'. Solution: If you're experiencing this issue, we recommend you try the following steps: 1. Make a small change on a page in the default language. 2. Save the page. 3. Then click to translate it again. This should trigger a new translation job and refresh the connection.
