"Security header is not valid" when trying to use Paypal Express Checkout

[Fredrik.r]

Hi,

 

I've installed Paypal Express Checkout on a osCommerce MS2 shop following these instructions;

 

http://svn.oscommerce.com/confluence/displ...%28asanAddOn%29

http://svn.oscommerce.com/fisheye/changelo...ommerce?cs=1699

 

When goint to checkout this error shows in the shopping cart;

 

"Security header is not valid"

 

 

Please let me know whats wrong if you know. Thanks

Anyone with this error?

I am getting the same error on my page.

 

The url is

https://www.mysite.com/shopping_cart.php?error_message=Security%20header%20is%20not%20valid

 

But before clicking on the PayPal buton the url is not secured (http://www.mysite.com/shopping_cart.php).

 

Any ideas on how to fix this error?

I think I discovered the fix. The error is coming from not having the correct API username, password and signature. Also, the sand box feature may not work. You need to obtain the API stuff from paypal.com (follow links about integration) and then update that in the admin control panel under module for paypal.

 

Here is a thread I found about this issue:

I have fixed the error page, but no other payment options are available during checkout (even though they are selected in the admin control panel. If you all know of a quick fix, please fill me in...Otherwise I'll be searching the forum again.

The quick fix for this is to change the zone to "none" in the payment modules. :rolleyes:
