I am trying to install phpfreechat on my website http://downloadfreemovies.org/ I have uploaded phpfreechat-x.x-setup.php from ftp in my root directory. Now as per instruction mentioned here http://www.phpfreechat.net/quickstart. but whenever i try to open copied link from directory i get error Parse error: syntax error, unexpected '?' in /home/shivcsco/public_html/downloadfreemovies.org/phpfreechat-1.2-setup.php on line 4. Can anyone guide how to install this chatroom on my website? Do i need any other software download on my computer such as php or Apache?
