To Reproduce
Steps to reproduce the behavior:
Create an advanced level selector page on the subscription choice page
Go to Subscription page
Choose a subscription level (click on "Subscribe" or "Renew")
On Checkout page, scroll down
See error
Expected behavior
No error should be displayed.
Isolating the problem (mark completed items with an [x]):
[x] I have deactivated other plugins and confirmed this bug occurs when only Paid Memberships Pro plugin is active.
[x] This bug happens with a default WordPress theme active, or Memberlite.
[x] I can reproduce this bug consistently using the steps above.
Additional information
The pmpro_checkout_after_form doesn't seem to be defined in Paypal & Paypal Express classes, nor anywhere else. I'm not sure these should be called here, or at all?
