Hi, Not sure if this is a proper bug, but when I assign something to $fd, instead of replacement it just add that value to the end: Let assume current $fd value is "mydomain.com" if I do following: $fd = "newdomain.com"; $fd changed to "mydomain.comnewdomain.com", but it should be "newdomain.com" I believe this is not proper behavior.
