PHP files won't run while haveing Xampp installed

[Empreez]

I have Xampp installed and running (supposedly) fine on Vista. I have started Apache from the Xampp control panel. When I type localhost/Xampp in IE it runs fine but whenever I try to run anything else it either fails or doesnt show anything.

 

For instance I copied all the file and folders from my working website to the htdocs directory in Xampp but I keep getting the error:

 

Fatal error: Call to undefined function initAll() in C:\Xampp\xampp\htdocs\index.php on line 26

 

Or whenever I try to run a very basic:

 

<?

phpinfo();

?>

 

I get nothing. Just a blank page.Anyone any idea what can be the problem? Everything else seems to work fine and when I look at the status in Xampp PHP is activated and phpinfo in Xampp shows all the info expected.

 

EDIT:

 

the phpinfo() code seems to work now.
