I found another bug. I think you forgot to update your database table for the new registration values.
exception 'Exception' with message 'MySQL Error: Unknown column 'user_show_empty' in 'field list': INSERT INTO `tbl_user` (`user_id`,`user_username`,`user_email`,`user_is_advanced`,`user_show_empty`,`user_remember_filter`,`user_realname`,`user_location`,`user_password`) VALUES ('','Blaze','ian@maide.ca','1','1','1','Ian','Ontario, Canada','Censored Password');' in /home/ron/public_html/ospap2/cls/clsDB.php:601
