 * Hi,
 * I have linked the PayPal Pro and Flow accounts. I am trying to test a payment,
   but I’m getting the following error, when I looks at the logs:
 * PCCG Paypal Pro Response Array
    ( [TIMESTAMP] => 2016-06-09T20:43:41Z [CORRELATIONID]
   => 5ee3a3b33f5df [ACK] => Failure [VERSION] => 121 [BUILD] => 000000 [L_ERRORCODE0]
   => 10002 [L_SHORTMESSAGE0] => Security error [L_LONGMESSAGE0] => Security header
   is not valid [L_SEVERITYCODE0] => Error )

 * Hello [@wasifhuda](https://wordpress.org/support/users/wasifhuda/),
 * It seems you are used incorrect PayPal sandbox credentials.
 * PayPal Pro required BUSINESS-Pro account and PayPal Flow required manager account.
 * Thanks!
