Had to hack to make it work on new registration

Overwrote code at registration section at line 200 with code from comment section

echo ''.$this->Settings->get( 'question' ).'
';
$Form->text_input( 'answer_turing_test', $tur_test_answer, 6, $this->Settings->get( 'answer_label' ), 'The letters are Case Sensitive', array( 'maxlength' => 6, 'class' => 'bComment' ) );
if( ! isset($params['form_use_fieldset']) || $params['form_use_fieldset'] ) {
$Form->end_fieldset();
}
