We're having a problem with our Billing Update Form for Stripe not working. I've double checked the shortcode generated by the Stripe Pro-Forms page of S2Member to make sure everything is fine with it, and made sure to have the most recent version of S2Member Framework and Pro installed on the website.
[12-Mar-2018 04:01:24 UTC] Stripe Notice: Undefined property of Stripe_Customer instance: subscriptions
[12-Mar-2018 04:01:24 UTC] PHP Fatal error: Call to a member function retrieve() on null in /web/content/wp-content/plugins/s2member-pro/src/includes/classes/gateways/stripe/stripe-utilities.inc.php on line 491
We have contacted Stripe about this and they have told us that this is an issue that S2Member needs to deal with.
