Contact Page Error 404

I followed the instructions in Rods Article for Setting up a WordPress based Backlight site. Is it nevertheless possible to make use of the Backlight Contact Page?
I get an page not found error although I have done all relevant settings I can imagine.
Insert Contact Form is enabled on that page. In the menu settings I have chosen an URL Link to contact/
Most likely this is not correct because my Site is not managed via BL?

If you’re basing your site on WordPress, you cannot create any Backlight pages, including a Contact page.

Use one of the many available contact form plugins for WordPress.
