The documentation for the folders 8.0 - 9.2 appear to not be present along with all the compressed tars.
The reason for the styling, formatting, problems is from 8.0 forward they are missing the reference to the docs.css style sheet. If you can put that in it will fix the problem.
Perhaps what should be considered to make things easier is just use jekyll to build the documentation and also put it under git control. I guess that would imply though moving it to the www repository.
