[moin-user] Moin 1.9.10:"permission denied" when I try to write page

[Renato Pontefice]

Hi,
I’ve finally installed MoinMoin (thank you to all)
But, when I try create a new page (simply putting the name of unexacting page) I reach the list of model pages I can create, or link to new white page.
But, if I click on a model or on a new page, I receive the message that I cannot create it.

I’ve already made a comode -R 777 to all the structure of wiki

Do I have to set some special variable?

TIA

Renato
