Прблема со страницей "Unsupported Browser" в Gantry framework - Joomla 3.x: Шаблоны, разметка и макеты вывода

По каким причинам это сообщение может выводится в "нормальных браузерах (chrome, mozila)"?

Unsupported Browser

We have detected that you are using Internet Explorer 7, a browser version that is not supported by this website. Internet Explorer 7 was released in October of 2006, and the latest version of IE7 was released in October of 2007. It is no longer supported by Microsoft.

Continuing to run IE7 leaves you open to any and all security vulnerabilities discovered since that date. In March of 2011, Microsoft released version 9 of Internet Explorer that, in addition to providing greater security, is faster and more standards compliant than versions 6, 7, and 8 that came before it.

We suggest installing the latest version of Internet Explorer, or the latest version of these other popular browsers: Firefox, Google Chrome, Safari, Opera

И как это устранить?

rt_cerulean, Joomla 3.0.3 , Gantry framework 4.1.7

Кто нибудь вообще знаком с gantry framework?

Частично решил проблему, отключением в панели управления gantry функцию заглушки ie7.
