      Hi – We take all payments through Paypal – most recent transaction yesterday.
      Trying to issue a refund – and receive the error ‘ Security Header is invalid ‘ – then the operation is cancelled.
      Given the above > all API credentials are correct.

      *after last update – which i confirmed with you before upgrading is ok – we receive the error that Templates are outdated.
