You need to enable short tags in your php.ini and restart your server as said by User016.
short_open_tag=On
It's been recommended not to use the short tag "short cut" and instead to use the full tag combination. With the wide spread use of XML and use of these tags by other languages, the server can become easily confused and end up parsing the wrong code in the wrong context. Also short tags may not be supported on the target server
