We recently set it so that members can sign up for a recurring donation. All of our payments for recurring donations are failing, though. You can see in the attached picture that there are three failed recurring payments. One of them is mine, and I know that I entered the payment information correctly, so the payment should not have failed. I've recently, successfully, made other payments on this site with the exact same payment information.
We recently upgraded to CiviCRM 5.3.2 from 4.6.28. We are using Drupal 7.60. We are using PayPal as our payment processor.
