In includes: page_header.php? I did it once and those errors went away when sending a message and such. I didn't really get the jist, if it was really ok do to that or not, in this topic.
If this will really affect others then I'll put those codes back and just deal with it I guess. But if it doesn't affect others then I will be a happy camper lol.
