Hi everybody!
I've set up my shopping cart to accept paypal express checkout and/or Paypal direct payments. My direct payment option seems to be working ok. But when I try to use the paypal express checkout, I get the following error and not sure why or how to fix it.
"Security header is not valid"
Any ideas?

Are you using the Sandbox server? I was getting the exact same problem when I was using (or trying to use!) the Sandbox server. The minute I switched to the Live server, it went away. Which doesn't really help me any because now I'm paying myself to test my cart, but at least it sort of worked - hope that helps any!
If anyone does come up with a solution that allows me to keep using Sandbox, please let me know!

I guess the only way is to remove the sandbox option. I did that and it worked.
Thanks Allybelle!
