i have a magento store running by bitnami on the AWS
i recieved an email from amazon telling me that i have to upgrade their database, so i followed the instructions here http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.OSUpgrades.html
then i got this error on the site http://smartkoshk.com/
i tried changing /etc/local.xml many times, it didn't work
i check the socket path in the database and in php.ini, they are identical
i deleted the magento cache under /var/cache, nothing changed
i restored the AWS to a snapshot i toke before the upgrade, and it still the same
so what is the problem?
