no, the data is set correctly (i've done var_dump to check). Cookies is working - if they wouldnt work - whole site would stopped functioning normally (user logins, etc..)
@jedd - i've tried not to echo anything but if i get redirect it means no flash variable is available..
Okay I replaced flashdata usage at this time, no time for research this time, but i will do that in near future, because this is very strange behavior which can affect my developed auctions site a lot.
