Fatal error on Magento 2 Site

[irukka_online]

I tried installing decimal price precision extension on my Magento site. the installation failed, though I did not do a backup because previous attempts at backing up failed. The failed installation threw up the following error messages:

Fatal error: Uncaught Error: Cannot instantiate interface Temando\Shipping\Model\ResourceModel\Repository\OrderCollectionPointRepositoryInterface in /home/irukkaon/public_html/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php:50 Stack trace: #0 /home/irukkaon/public_html/vendor/magento/framework/ObjectManager/ObjectManager.php(70): Magento\Framework\ObjectManager\Factory\Dynamic\Developer->create('Temando\\Shippin...') #1 /home/irukkaon/public_html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(144): Magento\Framework\ObjectManager\ObjectManager->get('Temando\\Shippin...') #2 /home/irukkaon/public_html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(230): Magento\Framework\ObjectManager\Factory\AbstractFactory->resolveArgument(Array, 'Temando\\Shippin...', NULL, 'collectionPoint...', 'Temando\\Shippin...') #3 /home/irukkaon/public_html/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php(34): Magento\Framework\ObjectManager\Factory\AbstractFactory-> in /home/irukkaon/public_html/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php on line 50

I have tried cpanel backup restore and it failed to restore, can I manually delete or alter any folder/file from cpanel to fix this error.

Thanks.

Hello @irukka_online 

try to remove generated/code and generated/metadata or run just setup:upgrade command it wil handle all thing.

Hope it will help you.

Thank you for your reply, my hosting company was able to manually restore the site to an earlier date.

Thank you.

open database and use this query:

DELETE FROM `eav_attribute` WHERE `source_model` LIKE '%Temando%'
