Paypal pro not working in virtuemart on joomla

[charanjeet]

Hii,

                   I am using virtuemart on joomla. I have created shopping card and using paypal pro in payment method. I am facing a problem that when i submit all details and confirm the order, page does not go further but reloads. Could someone tell me where i am going wrong.

 I am using Joomla! Version   Joomla! 3.5.1

                                                PHP Version     5.4.43

           I've developed the SANDBOX payment method, 2016 Method Test, with sandbox API credentials.  When attempting to checkout in the SANDBOX mode, the checkout page only reloads but does not enroll or proceed to a screen that indicates success of the transaction
