Then, go to your register.php file, find where it says:

PHP Code:

        mysql_query("INSERT INTO ".$prefix."users VALUES ('', '$username', '$pass1', '$email', '3', '1', '$date', '0')"); 


and place this at the very end:

PHP Code:

, '' 


So that it will looks like this:

PHP Code:

        mysql_query("INSERT INTO ".$prefix."users VALUES ('', '$username', '$pass1', '$email', '3', '1', '$date', '0', '')"); 


Why do we do this?
Let's let BMR777 explain that one:
Adding an extra field onto the users table requires you to edit register.php so the SQL query for creating a new user matches with the new database table structure. Failure to do this will BREAK the user registration system.
