Restore from automatic backup data Nov-6th.
Then the WordPress showed "503 Service Unavailable".
Changed the folder name "wpml-string-translation" to "wpml-string-translation-old", now I can access the WP page. Then back to the name and ACTIVE "WPML String Translation", back to "503 Service Unavailable".
