taksejimo Had been able to access your site now. On replicating the same on local install, Default template comes with custom font for which CSS constant has been defined in order to reflect here
To include the Icomoon fonts in this template, You can add this code to /templates/t3_bs3_blank/index.php at the end :
$doc = JFactory::getDocument();
$doc->addStyleSheet($this->baseurl.'/media/jui/css/icomoon.css');
and the icons shall reflect as envisaged
