Hi -
I've enabled Paypal Express module and added the API. When I go to test the API I get the following error message:
The requested URL /shop/admin/HTTPS_SERVER/shop/admin/ext/modules/payment/paypal/paypal_express.php was not found on this server.
the page paypal_express.php is not in the module folder - where can I find it?
I also get "secruity header is not valid" on the site when I test paypal payment.
Any suggestions would be appreciated!
