We've isolated the issue with logins/post redirects this morning to a configuration glitch in our front facing servers which inadvertently caused users to appear to be logged out from their accounts. Users who tried to re-login to their accounts were sent to forum-nevada.lowyat.net instead.
This issue has now been solved, and ideally you will not need to re-login to your accounts again at https://forum.lowyat.net. If you had logged in to forum-nevada.lowyat.net, there is no further action needed on your part as the issue has now been fixed.
