Using Civi 4.6.18 with Wordpress, we have event registrations working smoothly using the Paypal Website Payments Standard payment processor. The next stage is to get memberships up and running and we want to use Veda's UK Direct Debit/GoCardless payment processor to facilitate recurring membership payments.
However, as soon as I enable the Direct Debit extension (I've not configured it yet and it's not been enabled on any contribution pages), my event contribution pages, which are set up to use Paypal, stop working correctly because the billing block is no longer being displayed as it should be when the user chooses the 'pay later' option. As a result the user is faced with validation errors that they can't fix.
If I disable the direct Debit extension, my Paypal event registration form works as it should.
