Security header is not valid - not common issue?

jimnz · December 18, 2011

i get " Security header is not valid" when tiring to make a paypal payment

sandbox is "inactive" in paypal 2.4 module

yes the api credentials are copied exactly from paypal ( non sandbox mode)

payment type "direct sales" is set in module? i tried "authorization /manual capture" no difference

"paypal by credit cards" and "paypal express" options are ticked

i dont have a SSL setup

heres the error log:

Please refer to logs:

I had the same problem, try to generate new paypal API codes and replace them with the old ones. It solved my problem, so I hope it will work again.
