Getting this error when clicking on the paypal button on the contribution form:

Payment Processor Error message 10471: Transaction refused because of an invalid argument. See additional error messages for details. ReturnURL is invalid.

  • I tried deleting the paypal standard as a payment processor to see what would happen but clicking the button gives the same error.
  • what version of civicrm? what CMS?

You've probably done this, but the CiviCRM wiki provides instructions on how to set up the return URL for paypal.

  • Yup. It was working before I upgraded to 4.6.8
