Hi Guys,
Just repeating this from a similar post I made some time ago.
The simple way to get flash uploaders working is to set...
$config['sess_match_useragent'] = FALSE;
in your config file.
The CI session manager is getting a different user-agent from the flash component (as mentioned above) and deleting the session.
If you're worried about doing this, faking a user-agent string is so easy that this method doesn't offer much in the way of security anyway.
Good luck.
