Worked perfectly for me! Thank you!
I want a perfect copy of that website because a certain government will take
it down at some point. What other settings would you use?
I am confused by some settings like the depth etc. Could you take a few
seconds and take a look for me ? it's a huge website and I don't want to
download ANYthing but that website. No external ones etc.

Thank so much for your help.
