Hi, i followed this guide here: User Registration
now when i submit the registration i go to this url:

and this results in showing me my Error Page.
the problem here i have is that once i set the url parameter like here
<a <?php e($item->isOpen(), 'aria-current ') ?> href="<?= $item->url(['params' => ['login.referrer' => $page->id()]]) ?>"><?= $item->title()->html() ?></a>
it sets the parameter like such, example: http://kirby.local/registration/login.referrer;home
and so when the registration controller wants to set the parameter, it fails because the parameter is Null.
if ($referrer = param('referrer')) {
$kirby->session()->set('login.referrer', $referrer);
}
and this results in my lognRefferer not getting any value from the session
go('login/referrer:' . $site->loginReferrer());
this is my site method:
return kirby()->session()->pull('login.referrer') ?? '/';
what am i doing wrong ? Thanks a lot
