I checked the php compatibility with plugin “php compatibility checker” and for php version 7.1 there are these warnings on the Stripe Payments plugin – but no warnings for the Subscription Payments addon. After updating my site to php 7.1, the error is still happening as soon as I activate the addon. I don’t have sufficient knowledge to understand what, if anything, I can do to fix this.
