[CodeIgniter]Błędy przy nadaniu roli _check_perm Opcje

[agata]

Witam,
mam problem z rolami. Ogólnie role są rozpoznawane (admin/user) tylko w przypadku danej roli mam problem z wyświetleniem contentu z kodu poniżej:

Błąd dotyczy fuction index w którym otrzymuję komunikat : Message: Undefined index: content, Filename: controllers/site.php, Line Number: 107 (patrz komentarz).

Dziwne jest to że defakto wszystko jest wyświetlane poprawnie, tzn. jeżeli $perm = user -> wyświetla tylko "Zaloguj" (oraz błąd) a jeśli $perm = admin -> zawartość if (w tym momencie nie ma żadnego błędu).

Błąd jest tylko przy pierwszym ekranie i po wylogowaniu.

Nie mam pojęcia jak się pozbyć tego błędu proszę o pomoc i czym ten błąd jest spowodowany.

edit 1 :
udało mi się rozwiązać problem, co prawda metodą prób i błędów ale teraz działa.

W funkcji index() usunęłam kropki (.) przy response content a także usunięcie wartości True przy response->content = load->view.

Jak ktoś ma pomysł dlaczego tak się dzieje i czy może to zostać proszę o opinie.
