Why don't paypal appear

[mSale]

I check the \includes\classes\payment.php,trace it and find:

function selection() {

      $selection_array = array();

 

      if (is_array($this->modules)) {

        reset($this->modules);

        while (list(, $value) = each($this->modules)) {

          $class = substr($value, 0, strrpos($value, '.'));

          //moneyorder and paypal

          if ($GLOBALS[$class]->enabled) {

            $selection = $GLOBALS[$class]->selection();

            //only moneyorder

            if (is_array($selection)) $selection_array[] = $selection;

          }

        }

      }

 

      return $selection_array;

    }
