drupal 7 Ubercart recurring fee settings tab is blank
You may have to enable the module "Recurring - Hosted Gateways". This should be available under section "UBERCART - RECURRING" in the path admin/modules. In my case this is Paypal WPS.

Once the module is enabled you can see the option at admin/store/settings/recurring. You may also need to enable the required payment methods at admin/store/settings/payment.
