When using a product type parameter search, if a single value is returned from a 'multiple' field, a problem occurs in shop_browse_queries because the code expects an array
Line 218 should be changed from
$comp = " IN ('".join("','",$get_item_value)."')";
to
$comp = " IN ('".( is_array($get_item_value) ? join("','",$get_item_value) : $get_item_value )."')";

Thanks for fixing this and improving Product Type feature. I did the manual for Product Types :P you improve it.
