Whenever you had to restore a Prestashop website from backup, there are chances that you face the below error in the front end.

Fatal error: Uncaught Error: Class ‘Doctrine\Common\Cache\ArrayCache’ not found in /home/******/public_html/******/src/Adapter/ContainerBuilder.php:199

In such situations,

• Install a fresh PS on a subfolder (make sure the version is almost close to the one you have now)
• Rsync the following folders (or get those from https://prestashop.com/versions/)
  • cache
  • classes/cache
  • vendor/doctrine/cache
  • vendor/psr/cache

• Remove the cache files from var/cache/prod and var/cache/dev
