Hi
Your site is using outdated version of Joomla, that is officially not supported by Joomla too.
Also, all the extension and templates are oudated on your site. I suggest you to update all the extensions and template to latest version and migrate your Joomla to 3.x .
Take full backup of site before apply update as your site is still on Joomla 2.5 and very old version of GK template and extension.
