Empty HTML problem

Hello, I have a big problem around login script. I made an authentication site with PHP using PHP session. I use my own session handler that store session data into MySQL DB. It worked well on Win2000+Apache. But the problem occured when I put the scripts on TurboLinuxServer7+ Apache. login authentication script output nothing but -------------------------------------------------- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=shift_jis"></ HEAD> <BODY></BODY></HTML> -------------------------------------------------- It is almost empty HTML I have never expected!! Does anyone know about this kind of matter? Please HELP ME!!! I made php.ini as same as one of Windows. Regards, Hiroshi Ayukawa http://hoover.ktplan.ne.jp/kaihatsu/php_en/index.php
