Problem: After migrating a development site to production, the client encountered an error message stating 'Site Moved or Copied - Action Required.' This occurred because the WPML plugin was not properly migrated using WPML's migration feature. Solution: We checked the site and confirmed there were no critical errors. The error banner was due to an outdated version of WPML from before version 4.4, which was not compatible with the newer 4.8.2 version. To resolve this, we: 1. Installed the last 4.4.X version of WPML along with the latest version of the Translation Management plugin. 2. Ran the "move" option in the WPML settings. 3. Updated WPML to the latest version to ensure compatibility and prevent similar issues. We recommend following these steps for updating WPML in the future to avoid version compatibility issues: https://wpml.org/faq/updating-wpml-manually/
If this solution does not apply to your case, or if it seems outdated, please check the related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If the issue persists, we highly recommend opening a new support ticket for further assistance.
