Sent the test webhook and Stripe said it was sent successfully.
Viewed the log and all I see is:
[08/20/2020 8:58:14 PM] – Stripe Payments debug log file
[08/22/2020 12:16:04 PM] – [Sub] FAILURE: Stripe Subscription Webhook sent empty data or page was accessed directly. Aborting.
8/20 was when I turned debugging on and I assume 8/22 was the other day when I viewed the webhook URL in the browser.
Nothing in the log for today (8/24).
