The page I am trying to copy is a very simple but I am doing something wrong.
Regardless of what I tweak.

imagine a site like:
<https://test-test.de/>

It will only copy 
<https://test-test.de/>
But not
<https://test-test.de/home>
<https://test-test.de/bio>
<https://test-test.de/fun>
and so on...
I tried experiencing with the mirroring depth and external depth but none of
that helped. 
Please, what am I doing wrong?
