I am trying to use this software: [a href=\"http://stanxterm.aecom.yu.edu/secondary/stocks/index.php\" target=\"_blank\"]http://stanxterm.aecom.yu.edu/secondary/stocks/index.php[/a] Which uses [a href=\"http://www.dadabik.org\" target=\"_blank\"]http://www.dadabik.org[/a] I installed. Everything looks fine. But when I go to admin.php, my pages are blank-white. With the following errors: Notice: Undefined variable: head_extra in ./header.php on line 110 Laboratory of so and so - Laboratory of so and so - Lab inventory Notice: Undefined variable: log_status in ./header.php on line 129 Notice: Undefined variable: business_logic_included in ./interface_creator/check_login.php on line 58 Warning: Cannot modify header information - headers already sent by (output started at ./header.php:76) in ./interface_creator/check_login.php on line 63 And in other places, there are many errors. like Notice: Undefined variable: table in ./header.php on line 133 ------------- Could somebody please help me out?
