Clicking the "error page" link moves the process forward to the "Configure site" step but also outputs the following warning:

The block User login was assigned to the invalid region sidebar_first and has been disabled.

I have also attached the full dblog from the install, in case that is helpful: dblog.txt

The site does seem to work despite these issues, but blocks are not placed automatically in any regions.
