Not able to edit and update the products from magento admin. While trying to save the product I am getting the following error:
Recoverable Error: Argument 1 passed to Varien_Object::addData() must be of the type array, null given, called in ../public_html/app/code/core/Mage/Adminhtml/controllers/Catalog/ProductController.php on line 513 and defined in ../public_html/lib/Varien/Object.php on line 243
It was working fine few days back and stopped working all of sudden.
