And in your config.yml you need:
stripe_private_key_pattern: "sk_(test|live).{24}"
stripe_publishable_key_pattern: "pk(test|live)_.{24}"
app_encryption_key: “somethingRandomAndLongAndUniqueAndSecret”
Indeed the upgrade to 7.2.0 was supposed to enable Stripe automatically, but the conditions were a bit too strict and some manual steps can be required.
It’s true that it isn’t perfect, as the updated instructions are in the master branch but not in the Release 7.2.0. The work in progress prevents us to do a new release right now but following the instructions at https://github.com/sharetribe/sharetribe/blob/master/README.md#enable-stripe will work for the time being!
@karibu Your encryption key should remain secret, it’s best not to share it as someone could use it to read this data, so be careful not to share it in the future
