New Mediawiki install produces error “Fatal exception of type MWException”

  Saw this on a new Mediawiki install where all of the optional extensions were selected, LocalSettings.php had been uploaded to the server and that’s as far as it would go.   To fix, open up LocalSettings.php and comment out the line:  
require_once( “$IP/extensions/LocalisationUpdate/LocalisationUpdate.php” );
  You should now be able to refresh the main page and start using your wiki.
