Let's take COPS out of the equation for now and just focus on PageKite.
Can you save (with a text editor) the following code in a file named test.php:
Code:
<html>
<head>
<title>PHP Test</title>
</head>
<body>
<?php
phpinfo();
?>
</body>
</html>
and then place this file in ./web (not just like COPS with a symlink but straight in ./web)
What do you see (does it work) when you
http://192.168.xxx.xxx/test.php and
http://mydomain.pagekite.me/test.php?
