non-recoverable error on all new contribution pages

Just upgraded from 2.2.3 to 3.0.2. When I create a new contribution page, and then go to Test Drive or Live Page I get:

"Sorry. A non-recoverable error has occurred.

The requested online contribution page is missing a required Contribution Amount section or Membership section. Please check with the site administrator for assistance."

I did not specify any contribution amounts or memberships. Tried disabling all Civi components except for CiviContribute to no effect.

Debugging info:
