Hi,
Can you check that you have the file templates/YOUR_TEMPLATE/html/com_hikashop/product/listing_img_title_home.php ?
If that's the case, make sure that in the settings of your menu item, you've selected that img_title_home item box layout under the "products options" tab AND NOT under the "categories options" tab if you have it.
If all that doesn't help, try copying the file templates/YOUR_TEMPLATE/html/com_hikashop/product/listing_img_title_home.php to tcomponets/com_hikashop/views/product/tmpl/listing_img_title_home.php and see if this helps.
