i never noticed this but the tags are empty. i mean the products have tags and when i click on the tag the result is empty.

this is the exact comment.

$ret = $tagsHelper->postStoreProcess($tagsTable, $tags);
                if($ret) {
	$query = 'UPDATE #__ucm_content SET core_catid = 1 WHERE core_catid = 0 AND core_type_alias = \'com_hikashop.product\'';
	$db = JFactory::getDBO();
	$db->setQuery($query);
	$db->query();
}
