I am getting this error when testing a purchase on my new online shop:

Please refer to logs:

1. PayPal response:
2. TIMESTAMP -> 2012-12-04T19:14:25Z
3. L_ERRORCODE0 -> 10002
4. L_SHORTMESSAGE0 -> Security error
5. L_LONGMESSAGE0 -> Security header is not valid
6. L_SEVERITYCODE0 -> Error

Can anybody advise me, I can't find any help on the PayPal site.
