else run normal.

// logo file or site title param
if ($this->params->get('logofile'))
{
   $logo = '<img src="'. juri::root() . $this->params->get('logofile') .'" alt="'. $sitename .'" />';
}
elseif ($this->params->get('sitetitle'))
{
   $logo = '<span class="site-title" title="'. $sitename .'">'. htmlspecialchars($this->params->get('sitetitle')) .'</span>';
}
else
{
   $logo = '<span class="site-title" title="'. $sitename .'">'. $sitename .'</span>';
