display registration complete page

On my site there is just an test api for mollie, but in the testing the registrations are in the system on a right way.
But as a registrant i don't get the "display registration complete page". The system gets me an page in the menu " news"
where can I get an default registration complete page ore even better any self made page with a thank you message and additional info.

Hello

By default. the registration complete should be displayed after payment for the registration completed. In your case, maybe in the event, you entered a URL into Registration Complete URL setting of that event and that's the reason users are being redirected to that URL instead of the default registration complete URL ?
