Wordpress/WP Ecommerce Payment help?

[mikel2k3]

Hey guys,

Ive left a message in the WP Ecommerce support forum, but they seem to take absolutly ages to reply!
So maybe somebody else here has had the same problem and fixed or just generally knows the answer...


Ive just finished making the shop through Wordpress using WP Ecommerce, and everything is finally worked out and working great. I have managed to configure Paypal Express Checkout fine, however idealy for the site we need Paypal Pro to work (so the user isnt taken away from the site).
BUT! Im receiving errors after entering Credit Card details.
"Sorry your transaction did not go through to Paypal successfully, please correct any errors and try again.
Security header is not valid"

And lots of other paypal errors and such...

Any help appreciated as soon as possible!

Cheers guys!
