Dear Jan. Thank you for your kind and swift reply.
Now I can see the output of the specified fields - but ONLY IF LOGGED IN in Kentico.
My goal is that the visitors may see this, too. Why isn't the output displayed to unauthenticated users.
I checked if "display to roles" settings of the static text webpart were set to a certain value - but no.
This is what I see when logged in:

This is visible for unauthenticated users

Any ideas on this?
