Hi guys,

I wanted to create a new product today and got an error that is not configurable items available. The need very. Most items in my store are Configurable Products(Complex Product).

Please tell me how I can fix it urgently.

I have used your magento (quickstart) version installed.

ERROR: Fatal error: Call to a member function toOptionArray() on a non-object in app\code\core\Mage\Adminhtml\Block\System\Config\Form.php on line 463
