I've been meaning to post this problem. Yes, there seems to be a conflict with 6.02. I'm not sure what the deal is, but I'm working on it. The fix for now is to just reupload a clean public_common.pl file. You'll want to reupload clean copies of your templates if you've got the hack partially installed, for now, otherwise stuff might look a little funny.
I will post here when I figure out what the problem is.
