The Paypal Sandbox environment seems to be having troubles , whenever it redirects to PayPal - I am being asked to login. On clicking on the link , it redirects me to "developer.paypal.com" instead of "sandbox.paypal.com". Since it redirects to the developer site , I login with my developer account and then with the personal account credentials. Now , to place orders - i need to click the back button to reach the "Order Summary" Page and then click on "Order".
