Security Header Not Valid

Tony — Aug 08, 2016 08:40PM MDT

Having a problem in that when I hit the Confirm button, I get the following message:

ERROR: Security error. Security header is not valid

I have tried everything I could find in the Support Center and have had no luck. Can you help?

Hi Anthony.

If none of the troubleshooting tips help on (most notably the api keys and sandbox/live), then there may be an issue with your PayPal account. Sometimes I have had users report that some sort of an issue with their PayPal account was the cause. They usually fixed it with a call to PayPal. If nothing helps, please set me up as an admin user on the website and I will use my sandbox credentials and make sure it’s not your server (email login details to help a[t]~ Please don’t post the credentials here as this is a public post.

Thanks, Abel
