index.php shows up in url if form fails validation

[eluser]Flying Fish[/eluser]
I'm this .htacces rule to remove 'index.php' so I can have cleaner urls

but I've noticed that if I submit a form that fails validation, then index.php shows up in my url?

anybody know why?

form submits to the same page using

Code:

<?=form_open('/order/')?>

have you changed the 'index.php' line from the config/config.php file?

didn't realize I needed to do that too, will give it a shot

thanks!
