I am using Revive Adserver version 5.2.1. After deploying to AWS Beanstalk, I get many runtime errors, such as:
PHP Fatal error: Uncaught Error: Call to undefined method MDB2_Error::quoteIdentifier() in /lib/OA/Upgrade/VersionController.php
Although everything works fine locally, under the same code. Also works fine on a different infrastructure other than AWS. Is anything in particular needed to run at AWS?
