Autologin no longer working ?

Normally if I tick the "stay logged on" checkerbox I do not have to log in the forums each time, a cookie is set up so I can log in automatically, at least for one month or so.

Since today it seems that this function no longer works, and I have to log in manually each time. Am I the only one having this issue ?

It's a recurring issue. See viewtopic.php?f=13&t=10419.

That said, it hasn't been happening to me at all in a long time.
