Awstats issue

[Brujo]

I switched from Webalizer to Awstats, but it dosent works, so i tested it manually /usr/local/psa/admin/sbin/statistics --calculate-one --domain-name=my.domain
it seems Plesk didnt set the permissions correct and got the following errors:

Error: AWStats database directory defined in config file by 'DirData' parameter (/srv/www/vhosts/my.domain/statistics/webstat/current) does not exist or is not writable.
Setup ('/usr/local/psa/etc/awstats/awstats.my.domain-http.conf' file, web server or permissions) may be wrong
