Hi,
The registration page indeed doesn't support that setting. At the moment only the categories and products listings support it.
We'll look into it for the next version of HikaShop. Thanks for your feedback.
In the meantime, you can manually add the code:
$robots = $params->get('robots');
if (!$robots) {
$jconfig = JFactory::getConfig();
$robots = $jconfig->get('robots', '');
}
if($robots) {
$doc = JFactory::getDocument();
$doc->setMetadata('robots', $robots);
}
after both lines:
hikashop_setPageTitle($title);
in components/com_hikashop/views/user/view.html.php and it will do it for the registration page.
