Hoov, even if that fixes NSX's problem, I still suspect there might be a cookie related problem at the agoracom end as well.

Because I've had the same problem even though my cookies are always turned on and I log out properly etc.

For me, the problem has come and gone more or less at random. And it appeared for the first time maybe 2 weeks ago ... prior to that, going back I guess a year or more, everything was fine.
