SOLVED Setup complete but can't login or see site

[Tyblitz]

Aha, it seems your server is configured with CGI. See the answer to the question in this link: http://stackoverflow.com/questions/14555...-specified. It seems quite complicated to setup correctly (I have no experience with it).

Now I think you're very likely running on Windows/IIS (not Linux/Apache), because the error 'No input file specified' is linked to this setup. Can you verify this? If it is the case, have a look at http://get-simple.info/wiki/installation:requirements; which says you need a Linux host with Apache for GS to work.
