If you have a former subscriber who is no longer paying and wants to purchase a subscription again, in rare cases they may be unable to do so.
This happens when the subscription plan has a Free Trial enabled
If a subscriber has ever signed up for a plan that included a free trial, Leaky Paywall will prevent them from subscribing again to avoid repeated use of the free trial.
To allow the subscriber to purchase the subscription again, you’ll need to disable the free trial on that plan.
