Webdav with permalink in WordPress v3.3.1

I´ve found my own answer for this problem, I’ve edited my /site-avaiable/default/, added Alias /webdav "/var/www/webdav" And I’ve moved my folder to /var/www/webdav/, now its working when I try to access it by using http://10.0.0.36/webdav.

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
