PROCESS ORDER ERROR MESSAGE

[Nick Winters]

I get a very strange error message when I try and process my orders while using virtumart. The error messages are as follows:

Error - Paypal did not complete order - LONGMESSAGE=Security header is not valid - ERRORCODE=10002 -

Error: Error - Paypal did not complete order - LONGMESSAGE=Security header is not valid - ERRORCODE=10002 -
Error: Failure in Processing the Payment (ps_paypal_wpp

Error - Paypal did not complete order - LONGMESSAGE=Security header is not valid - ERRORCODE=10002 -


Can someone PLEASE help me out with this. It has been extremely frustrating. I'm on a Joomla site and I'm using PayPal Pro US component as well. Not sure what is happening.
