Help with simple routing please?

It was a problem with 1and1 host. So FIY 1and1 not good for Codeigniter. I tried a different host and it works just fine. I can't believe I wasted so much valuable time.

Do the one thing you think you cannot do. Fail at it. Try again. Do better the second time. The only people who never tumble are those who never mount the high wire.
