Please Please HelpUm, are you sure this is PHP5 you're talking about and not 4?In either case, I think your problem is that the class is specifying variable and such as "public" or "protected". From what I've heard, PHP doesn't support public/private members of a class. Maybe it does in PHP5, but if you're running PHP4, that's your problem.
