New user signup redirects to home page after registering account

Here's the sequence of events:

1. New user clicks to signup for a plan from /signup

2. User is directed to the create account page and user creates new account.

3. The page redirects to the home page instead of going to the payment page.

As a logged-in user, if I go back through the process I will see the payment page. This is a new bug since installing version 3.4.5.
