Foro phpbb3

[Gunmanspeed]

Estoy intentando instalar un foro phpbb3 y esto es l oque me sale y no me deja continuar quiere decir que, mi servidor no tiene, permisos de escritura o algo asi?

Código PHP:

Files and Directories
 
Required - In order to function correctly phpBB needs to be able to access or write to certain files or directories. If you see “Not Found” you need to create the relevant file or directory. If you see “Unwritable” you need to change the permissions on the file or directory to allow phpBB to write to it.
 
cache/:
    Found, Unwritable
 
files/:
    Found, Unwritable
 
store/:
    Found, Unwritable
 

Gracias a los que respondan de antemano.
