Robert thank you very much for your quick response.
It works now, I forgot to customize the php file.
I have another question:
If you see my new screenshot, I will wish to add an image to the top of the article as the template. For “pages” is possible when I use “Pages options” > “Background Image” field and > “additional image”. In contrast to the “post” feature is not found, do you know where I can add the image for “post”?
