I am having issues processing payment through the forms

When you go to submit payment and submit the form, it says that there is something wrong with the credit card. This can't just be an individual credit card issue, as all of our participants have had the same issue and no one has been able to submit the form. 

Are you referring to this form:

Is this form embedded on any website? If yes, could you please share the website link.

Please share the screenshot of the error message.

Also, you could try disconnecting the payment integration and then connecting it once again.

Thanks.
