test it please

Hi, I've written a PHP guestbook with the slight twist of it not requiring a database. Anyway, I would appreciate it if someone would download the source code, and then try it out on their own server. I am asking this because I tried it on f2s.com (a free PHP webspace provider) and it did nothing but spout error messages - complaining that safe mode was on. But safe mode is on in my other sites and it works fine! Weird. Anyway, you can download the code from this address: http://www.webmastersdog.com/PHPapps/guestbook/guestbook.php Please tell me if it does or does not work + plus any error messages AND please tell me the version of PHP you are using (this was built under 4.0.6) otherwise the information you give me will be useless. Thanks! ++++++++++++++++++++++++++++++++++++++++ http://www.webmastersdog.com where website owners go. and talk about stuff. ++++++++++++++++++++++++++++++++++++++++
