Hi

I have always used opencart PayPal express checkout without problems.

Now on a new opencart install I get error "Security header is not valid"

Any ideas please ?

Thanks

Try the latest OC version on a test folder and see if the same issue can be replicated. I did received a newsletter email from PayPal, this week, regarding the new PCI-DSS compliance policy that requires the change to PayPal's API.

Dedication and passion goes to those who are able to push and merge a project.
