Ah. And i found little mistake in plugin jamegafilter for joomshopping. in helper.php.
Its about old price section. In your file code is:
if ((int)$baseItem->product_old_price) {
$old_price = $baseItem->product_old_price / $productCurrency * $config->currency_value;
$item->frontend_old_price = number_format($old_price, 2) . ' <span class="currency">' . $currency . '</span>';
}
I think it must be like this:
if ((int)$baseItem->product_old_price) {
$old_price = $baseItem->product_old_price / $productCurrency * $config->currency_value;
$item->frontend_old_price = number_format($old_price, $jshopConfig->decimal_count, $jshopConfig->decimal_symbol, $jshopConfig->thousand_separator) . ' <span class="currency">' . $currency . '</span>';
}
