Problem: The client is unable to add a site key to their new development website hosted locally on a MacBook. Despite trying various troubleshooting steps like downloading the latest installer, disabling the firewall, deleting and creating a new site key, and using a VPN, the site key is not accepted, and the error 'Unable to parse data from service response' appears. Solution: If you're experiencing similar issues with adding a site key on a localhost setup, we recommend following these steps: 1. Review the recommendations in this public ticket: https://wpml.org/forums/topic/unable-to-parse-data-from-service-response-46/ 2. Navigate to WPML > Support > Installer support in your WPML dashboard and click the 'check' button. Check if there are two green check icons at the top. If there are any red X-ses, it might indicate a block on our end. 3. If you see red X-ses, share your IP with our support team so we can check for any blocks. 4. Our Systems team may need to intervene if there is an IP block, as was the case here, where after intervention, the issue was resolved.
Please note that this solution might be irrelevant if it's outdated or not applicable to your case.
