Usually "Security Header Not Valid" means that the API credentials that were entered are not correct.

Re: " Refund not going through woocommerce"

I have exactly the same problem! Payments work, only refunds do not.

Kindly asking for a professional reply! Thanks in advance! 

did check all the API-settings (and IPN) in the woocommerce plugin (called paypal standard), and still no change. We also tested from different locations (even countries) and computers.

this is my log:
