I get this error when I try to export clients through System> Import / Export> Export . How to fix?
The reason was the plugin: Tax Code and Privacy http://www.magentocommerce.com/magento-connect/tax-code-privacy.html .After deletion, he left the βprivacyβ attribute for the client object.
The solution was to manually delete the attribute in the Magento eav_attribute database table.
, "attribute_code" "".
