Hi,
The latest version is still 2.2.2 but there was some fixes in this version, so there is different versions of the 2.2.2.
So thanks to download the latest package from our website and install it over your current HikaShop version.
Else you can use this MySQL request in a view for example, and then go on a page where there is this view and then remove this code from the view. (to edit a view you have to go through the menu Display > Views).
<?php
$db = JFactory::getDBO();
$db->setQuery('REPLACE INTO '.hikashop_table('config').' ( config_namekey, config_value) VALUES( "enable_wishlist", "0" )');
$db->query();
?>
