ragazzi sono due giorni che litigo con phpbb e tutte le volte mi da questo errore:

Warning: main(): Unable to access ./../extension.inc in /membri/konohafansub/forum/install.php on line 297

p.s. ogni volta che provo a cambiare il permesso d'accesso a config.php mi dice che il server non ha bisogno di questa opzione.

Vi prego aiutatemi! :░░░
