I am testing on a new website and have some issues using a Paypal hosted button. I am using the sandbox for testing. I can successfully use the IPN tester against my site with no issues. I can click on the purchase button and make a fake purchase with no issues, but wp-stamper does not generate a file. It is my understanding it should work even though I am using the paypal sandbox. Is there a log file I can look at for additional troubleshooting.
Thank you,
Vic
