I just created a webform with a Civi contribution page enabled. When I save the form to test, the payment options are not showing as part of the form. Do I need to do something other then enabling the contribution section and assigning it a contribution page to get the credit card and billing address fields to show?
Presumably you are on 7.x-4.15 of webform_civicrm since you say you just upgraded. If you switch back to 7.x-4.14, does it work? If so, it looks like the same issue I logged here: https://www.drupal.org/node/2676752
With the fixes outlined here: https://civicrm.stackexchange.com/a/18449/930
The payment fields should work in webform version 7.x-4.18 with CiviCRM 4.7.18.
