Whenever a user attempts to purchase a subscription membership from the website, the transaction fails. After pressing submit, the form displays, "Sorry, your signup request has failed. Try again."
Also, the page throws an error at the top of the page that says, "Class not loaded: ReallySimpleCaptcha Class not loaded: MarketPress_MSClass not loaded: MarketPress_MS"
We are using the Authorize.net sandbox payment gateway. We've tried with secure transactions toggled on and off (requires ccv every transaction). Any insight you can provide would be greatly appreciated. We'd really rather use Membership 2 than Paid Memberships Pro.
