I just upgraded from 220.127.116.11 to 1.9.3.
But now i'm facing 3 major problems.
1.Mandrill suddenly stops sending emails (Order Confirmaion , Account
Registration , Newsletter etc)
2.Customers are unable to register . Screen refreshes but stays on the same page.
3.Other websites are unable to fetch data (Importing Orders).
I'm new at magento & tried my best but couldn't able to solve these issues.
Is anyone there who is facing same issues after upgrading to 1.9.3
