[KarandeepArora]

Hello all

After Data migration from magento 1.8.1.0 to Magento 2.0.7  . After login from user account I am getting Fatal error: Call to undefined method Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend::getAllOptions() in /var/www/html/magento2_new/vendor/magento/module-customer/Model/AttributeMetadataConverter.php on line 68. Can anybody help me

Thanks

To fix it, I ran the recursive command to ensure that the Apache service has read permissions.

sudo chmod -R 755 ~/Sites
