white php page

G'day All

Please appreciate it if any one can help

I just installed the latest fedora 18. When I go into my website everything works fine until I go into the video page which has php melody installed so I can play videos on my website. The problem is that the page is blank. I have tried everythink, like re-installing my mysql tables, checking the php.ini file is good.

Can anyone please help

Thank-You
