Hi everyone

I have been using this tut > http://www.ssbits.com/tutorials/2009/custom-login-form-with-group-based-redirection/

And we did have a perfectly working site, however it seems to error now!

[User Warning] Already directed to /admin; now trying to direct to /
POST /Security/LoginForm

Line 464 in /var/sites/c/cmpe.co.uk/public_html/sapphire/core/control/Controller.php

458 	/**
459 	 * Redirct to the given URL.
460 	 * It is generally recommended to call Director::redirect() rather than calling this function directly.
461 	 */
462 	function redirect($url, $code=302) {
463 		if($this->response->getHeader('Location')) {
464 			user_error("Already directed to " . $this->response->getHeader('Location') . "; now trying to direct to $url", E_USER_WARNING);
465 			return;
466 		}
467 
468 		// Attach site-root to relative links, if they have a slash in them
469 		if($url == "" || $url[0] == '?' || (substr($url,0,4) != "http" && $url[0] != "/" && strpos($url,'/') !== false)){
470 			$url = Director::baseURL() . $url;

_config includes

//custom login
Object::add_extension('Group', 'GroupDecorator');

Any ideas how to fix this? Thanks!
