Membership 2 Stripe Subscriptions Configuration and Checkout Not Working

We’re having some technical issues with our install. The Stripe Subscription Gateway doesn’t seem to be working in the admin area (there aren’t any configuration options) and when you go through the signup process, there are no payment fields. I've tried a different theme and turning off all the other plugins. The site is a password protected staging site, so I'll need to get you that info by way of the Contact form. Thanks!
