I'm trying to download a site where a lot of the pages are a producing a http
500 internal server error ( (500) after 2 retries  )

They render fine on a browser. e.g. Firefox, and I have checked that it is
indeed generating a 500 error regardless of what browser I use. Not caused by
WinHTTrack overloading it. It is likely a server problem (Drupal) that I
cannot fix from my end.

Any way it can save AND follow links on a rendered error page?
