Well since the automatic route didn’t work I’ve changed the default theme to manually add the products and regular contents for the newsletter.
Unfortunately it seems to work just fine on my offline test server but when I shift to the production server the preview window shows the 404 page instead of the newsletter.
If I click on ‘Go to edit this message’ It shows ok, but the nagging part is that during the newsletter creation one can’t see the preview.
The URL is this.
Anyone?
