Sometimes SQLite is not an option and I created FlatDB for my own needs. This is not a replacement for SQLite or other database engine.
So now curiosity has gotten the best of me... is this a private lan or something? The only thing I can think of it is one of those situations where a University gives you a website but it is really really locked down.
Also, try starting it with a dot (".mytest.html") as a lot of servers prevent hosting up files that start with a dot.
