 * I tried to refresh the WordPress installation – uses Godaddy wordpress installations/
   refresh . But no go. I have disabled to plugins and switch Template – still getting
   same error.
 * I tried to follow YOUR instructions but it is unclear how to reinstall from within
   Godaddy.
 * You write – Replacing with the latest wordpress files helped. it is the automatic
   update setting caused the issue. Now my site is back. Thanks.
 * Detailed guidance appreciated. I spent 60 minutes with godaddy website hosting
   support, but after trying everything they said I should reinstall.
