I'm currently running php 4.3.11 and have been trying to upgrade to 4.4.4. This is the file I download to install: http://us3.php.net/get/php-4.4.4-Win32.zip/from/a/mirror I try these instructions: 1. Download zip distributive of the php 4.4.4 (not binary installer) 2. Unzip to any folder on the desktop 3. Go to the c:\program files\swsoft\plesk\additional. There you will find the old php folder. Back it up, I copied it to the same folder and called it Php.4.4.2. After that delete the contents of the old php folder and copy/paste (not move) the content of unzipped php4.4.4 to there. After I follow the instructions no php pages load and if I type a full url to a php file it will try to download it. Am I missing a step?
