! Undefined index on 404 errors. (QueryString.php)
! There's a strong chance MID isn't defined at the time it's tested against in is_not_banned. Never generated an error for me, but better safe than sorry... (Security.php)
! Made title classes a bit less horrible in Wine. I really need to rework this skin... (Wine/extra.css)
! Ah, the serialize bug... I've worked hard on this. I reproduced the original conditions. I was completely unable to trigger it again. It looks like I'm the only one who got affected by it, so... I'll be praying that it doesn't happen again, and in the meantime, I'm adding a solution that seems to work if the bug happens again. I don't want to waste any more time on this when I have so much work left to do. (Class-System.php)
