SWF Upload + CodeIgniter

I've got the same problem.

Everything works great in IE, but in the other browsers it seems that it doesn't get to the URL at all.

Tried de debug mode (returns no data) and with firebug I don't get anything back either.

Does someone know how to fix this?

*******EDIT********
Found out what went wrong. It was a session problem. In my constructor I check if a user is logged in. If not, It does a redirect. Because of the session thing with flash it doesn't work, because I haven't got a session and because of the redirect I don't get an error message.
