Thread:Project:Support desk/extension:centralauth settings

hi what should I set this $wgConf->fullLoadCallback = 'wmfLoadInitialiseSettings'; as because this wmfLoadInitialiseSettings was removed from mediawiki and I get these errors

Warning: call_user_func expects parameter 1 to be a valid callback, function 'wmfLoadInitialiseSettings' not found or invalid function name in /home/paladox/public_html/en/includes/SiteConfiguration.php on line 595
