Form submit using wrong path

[eluser]williamparry[/eluser]
Hi,

I have a registration page and the top of the html in the view folder is:

Code:

<?=form_open('register'); ?>

In the controller folder I have:

Code:

<?php

class Register extends Controller {
    
    function index()
    {
(etc)

The page is located at:

http://127.0.0.1/website/index.php/register

When I submit the form, it goes:

http://127.0.0.1/website/index.php/regis...p/register

Why is appending the index.php again?

Thanks
