It was easy.
In product.php change old code to this:


// === Next - Previous products from xCartMod.com ===

$mem_list = func_query("SELECT pr.productid, pr.product, mem.membershipid FROM $sql_tbl[products_categories] AS cat, $sql_tbl[products] AS pr LEFT JOIN $sql_tbl[product_memberships] AS mem ON mem.productid = pr.productid WHERE cat.categoryid = '$product_info[categoryid]' AND pr.productid = cat.productid AND pr.forsale='Y' ORDER BY pr.product");

$list = array();
if (is_array($mem_list))
foreach($mem_list as $li) {
if ($li["membershipid"] == $user_account["membershipid"] || $li["membershipid"] == 0 || $li["membershipid"] == "")
$list[] = $li;
}

if (is_array($list))
foreach($list as $x=>$li)
if ($li["productid"] == $productid) {
// previous
if ($list[$x-1]["productid"] != "")
$prev = $list[$x-1];
else
$prev = end($list);

// next
if ($list[$x+1]["productid"] != "")
$next = $list[$x+1];
else
$next = $list[0];
}

$smarty->assign("next", $next);
$smarty->assign("prev", $prev);

// === Next - Previous products from xCartMod.com ====
