There's apparently a bug with cookie expiration, which is a new feature that makes a cookie invalid if the member doesn't log in for the specified length of time. It was causing some members' cookies to become invalid unnecessarily (it doesn't affect everyone). I disabled the feature until a patch is available, and I believe that this will allow for everyone to stay logged in.
For those who were experiencing the problem, please delete your cookies set by CurvedSpace. There's a link at the bottom of the board index that will do it for you. You could also hit the "Logout" button I added at the top. Then log back in.
If after clearing your cookies (and logging back in) you still experience the issue, please let me know. Thanks
