Custom PHP - Prevent vBulletin from timing users out?

[WorldCraft]

For some reason it's causing errors to occur. I am placing the function call under my global.php call - require(AJAX_CHAT_PATH.'../global.php');

This is what I get when trying to access the chat when already logged in to the forums:

Query: SELECT userID, userName, userRole, channel, UNIX_TIMESTAMP(dateTime) AS timeStamp, ip FROM ajax_chat_online ORDER BY userName; Error-Report: Error-Code:

If I try to go to the chat and try to login directly, I get this database error:

Database error in vBulletin 4.2.0:
