Site name and category name?

Hi,

That is controlled by the option "Include Site Name in Page Titles" in the configuration of Joomla. If you set that to no, it won't display the site name.

You can alternatively remove the code:
if (empty($title)) {
$title = $app->getCfg('sitename');
}
elseif ($app->getCfg('sitename_pagetitles', 0) == 1) {
$title = JText::sprintf('JPAGETITLE', $app->getCfg('sitename'), $title);
}
elseif ($app->getCfg('sitename_pagetitles', 0) == 2) {
$title = JText::sprintf('JPAGETITLE', $title, $app->getCfg('sitename'));
}

from the files components/com_hikashop/views/product/view.html.php and
components/com_hikashop/views/category/view.html.php to remove the
site name from the title on products and category listings.
