[quote]So my next attempt will be to set remember-me expiration for 6 months instead of 12 months in case there's an issue with too-far-ahead expiration.[/quote] That'd be strange, given that this computer has managed to logged on on some sites ever since it was bought (so two years ago), and all the dumb php-session and cookie-solutions I myself have made have ended up using being pretty reliable (for me, even if they may not always be to others, as has turned out)... I'd suspect it's something even more elusive. But hey, we'll wind up finding out whether anything changes the next time I have to restart something or another.
