Description of my issue:
I saved the site www.whera.org.uk through the backend before running a migration tool to upgrade to Joomla 3.3. Save completed normally as usual. The upgrade failed so I ran kickstart.php as I have many times, and it completed successfully. The site does not come up with a 500 Internal Server error on the front end. GoDaddy say there is nothing in their logs, and in the backend with the following error:
Fatal error: Call to undefined method JAdministrator::setHeader() in /home/content/35/11892335/html/whera.org.uk/libraries/cms/html/behavior.php on line 712
