After the installation of Phppgadmin in ubuntu by apt-get command, and while starting the apache2 star command, I am getting the following error:

config.inc.php:1: <?php> was not closed.
Action 'start' failed.
The Apache error log may have more information.

I ensured that <? php is at the first line and ?> at the last line of config.inc.php. I am also not able to locate the relevant apache error message.

OS - Ubuntu 12.04

Please help to resolve the problem.

Thanks in advance.
