: PHP not working : Ubuntu I have a problem my test server loads html files fine but when I try to open a file like index.php it says The website encountered an error while retrieving http://localhost/.

I have a problem my test server loads html files fine but when I try to open a file like index.php it says The website encountered an error while retrieving localhost/. It may be down for maintenance or configured incorrectly. I have PHP5 installed but I don't see why this isn't working, is it an outdated PHP problem?
