Problem: The client was experiencing issues with WPML updates failing due to the hosting server's inability to whitelist certain domains necessary for the updates. Solution: We recommended that the client ask their hosting provider to whitelist the domains: wpml.org, cdn.wpml.org, and api.wpml.org. Additionally, updating OpenSSL on the server might resolve the issue. If the hosting provider is unable to whitelist these domains, we suggested manually updating WPML by downloading the latest versions from https://wpml.org/account/downloads/ after creating a full website backup and removing the existing WPML plugins. Alternatively, changing the hosting provider could be considered.
If this solution does not apply to your situation, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 issues persist, please open a new support ticket at WPML support forum for further assistance.
