How did you even notice that !
You will need to edit your PortalMain.controller.php in the sources/controllers directory
public function pre_dispatch()
{
global $context;
if (!sp_is_active())
{
redirectexit();
}
$context['page_title'] = $context['forum_name'];
public function pre_dispatch()
{
global $context, $txt;
if (!sp_is_active())
{
redirectexit();
}
$context['page_title'] = sprintf($txt['forum_index'], $context['forum_name']);
