Yep, I'm not sure how that got changed, but it should read:
WHERE title=
'maxloggedin
'");
That's the code that will update the maximum number of online users if a new record is set. I'm not sure how it got changed though as it was correct in v3.2 and prior... Either way if you'll just add the ' marks around maxlogged in it should fix the problem, and I've also updated the zip file in the first post.
