Problem with _remap function (trying to redirect) [SOLVED]

[eluser]tommizzle[/eluser]
Hi andrew,

I just tried the redirect - still no good

I have tested is_valid_user() on it's own like this:

if($is_user == false):
echo 'false';
else:
echo 'true';
endif;

it returned false on the homepage, and 404 when i tried to put a username after the www.root.com/

I think I'm definitely being insanely stupid somewhere here.

Thanks for your help,

Tom

Edit: I just tried hardcoding $is_user to true, and still got a 404 when i put a username on the end.
