Completely Remove Module in magento1.9

Question

I installed a module with Magento Connect. After install, I found some errors in the backend and removed it from Magento Connect, refreshed, reindexed and cleared cache but still have the error.

When I click to add a new product I see this error:

There has been an error processing your request

and the file in var/report show

a:5:{i:0;s:100:"Source model "marketplace/catalog_product_attribute_status" not found for attribute "product_status"";i:1;s:3088:"#0 C:\xampp\htdocs\asai\app\code\core\Mage\Eav\Model\Entity\Attribute\Abstract.php(387): Mage::exception('Mage_Eav', 'Source model "m...')
1 C:\xampp\htdocs\asai\app\code\core\Mage\Adminhtml\Block\Widget\Form.php(201): Mage_Eav_Model_Entity_Attribute_Abstract->getSource()

How to repair it?
thanks.

Answer 1

Seem as a product attribute product_status was added by this extension.

Go to Admin - Catalog - Manages Attributes and delete this attribute.
