Akeeba Kickstart will stop supporting your version of PHP very soon. You must very urgently upgrade to a newer version of PHP. You can check our Compatibility page to see which versions of PHP are supported by each version of our software, select the newest one that fits your site's needs and upgrade your site to it.
