Hello-
I have gotten this error after correctly setting up the Stripe payment add on. While waiting for support to write me back; I seemed to have solved the issue so I am writing this for the next person looking. Here are the two solutions (explanations) I found:
- The amount you are testing is too low. For US credit cards I believe it needs to be over $.50.
- The page is being cached. I suspended caching for the page which had the form on it and payments started going through just fine.
