i found out that if i use CDN subdomain i get false positives no matter what. I use mirror settings in W3 Total Cache so i have duplicated files on server. It is not important too much but maybe somebody have same little issue. Second thing, when i check out all notification (i do not want to get any email) its look great in options when i save it, but when i refresh page i get ticked 4 options for notification email.
By the way this is a great plugin :)
