    63     Your server doesn't have support for PHP 5.

    64   </h2>

    65   <p>

    66     PHP 5 is the latest version of the language on which Enano was built. Its many new features have been available since early 2004, yet

    67     many web hosts have not migrated to it because of the work involved. In 2007, Zend Corporation announced that support for the aging

    68     PHP 4.x would be discontinued at the end of the year. An initiative called <a href="http://gophp5.org/">GoPHP5</a> was started to

    69     encourage web hosts to migrate to PHP 5.

    70   </p>

    71   <p>

    72     Because of the industry's decision to not support PHP 4 any longer, the Enano team decided that it was time to begin using the powerful

    73     features of PHP 5 at the expense of PHP 4 compatibility. Therefore, this version of Enano cannot be installed on your server until it

    74     is upgraded to at least PHP 5.0.0, and preferably the latest available version.

    75     <!-- No, not even removing the check in this installer script will help. As soon as the PHP4 check is passed, the installer shows the

    76          language selection page, after which the language code is loaded. The language code and libjson2 will trigger parse errors under

    77          PHP <5.0.0. -->

    78   </p>

    79   <p>

    80     If you need to use Enano but can't upgrade your PHP because you're on a shared or reseller hosting service, you can use the

    81     <a href="http://enanocms.org/download?series=1.0">1.0.x series of Enano</a> on your site. While the Enano team attempts to make this

    82     older series work on PHP 4, official support is not provided for installations of Enano on PHP 4.
