I am encountering a strange issue with PayPal Express checkout. I have configured PayPal express checkout on website. Every thing is configured correctly as per my knowledge.
The problem I am facing is, When user pays using Express checkout he/she is successfully redirected to PayPal website and are allowed to pay.
After payment, when user is redirected back to Magento i am getting an error "Unable to initialize Express Checkout". However, the payment is already done and reflected in PayPal. Also, the order is being placed in Magento admin.
For better clarity, I have inserted below PayPal log
