Customer Gets Error when Paying on Form using Stripe

Hi I have a customer that called and said she gets the error on the screenshot below. Did I do something weird when I was setting up the form? I can't figure out what might be causing it. She said that she has confirmed with her bank that the error is not with the card. I also had another customer report that they had gotten an error but didn't get the full details because I thought it was just because I was still working on the form. This screenshot was taken once the form was complete.

I was able to reproduce the problem as well when I test your form on the website.

As indicated on the error message, it seems that your Stripe account API key was already expired.

It seems that your form is connected with Stripe using outdated API keys. I would like to suggest adding your current Stripe API keys via Payment Wizard.

[Stripe] Where do I find my API keys?

To run the form in a test mode use Test keys, and when you are ready switch to the Live keys.
