Quote by Nightdude: Error log shows "Failed to set session cookie"
This error message is only used once, in lib-sessions.php, when Geeklog tries to set the user's session cookie. Which means that the setcookie() call there failed.
The PHP manual has this to say about the return value of
setcookie():
If output exists prior to calling this function, setcookie() will fail and return FALSE.
So, to cut a long story short: Something somewhere has emitted something before that setcookie() call. Sounds like a typical whitespace problem ...
