Thanks for your answer. It seems that the adding of a “Display Product Catalog” component does not work. After adding the component and filling out the parameters on the right hand site (catalogue id, starting layout), the resulting page is empty. And: “Edit as HTML” brings up an empty field.
When I instead manually add
[product-catalogue id=”1″ starting_layout=”list”]
to my page, it works.
