Hi,
Unfortunately, the patch that Xavier gave you is not the right one.
Please edit the view "product / variant" and replace
<?php if(hikashop_acl('product/variant/price')) { ?>
By
<?php
$curr = '';
$mainCurr = $this->currencyClass->getCurrencies($this->main_currency_id, $curr);
?>
<dt class="hikashop_product_msrp"><label for="data_variant__product_msrp"><?php echo JText::_('PRODUCT_MSRP'); ?></label></dt>
<dd class="hikashop_product_msrp">
<input type="text" id="data_variant__product_msrp" name="data[variant][product_msrp]" value="<?php echo $this->escape(@$this->product->product_msrp); ?>"/> <?php echo $mainCurr[$this->main_currency_id]->currency_symbol.' '.$mainCurr[$this->main_currency_id]->currency_code;?>
</dd>
<?php if(hikashop_acl('product/variant/price')) { ?>
And you should also update the product class "administrator/components/com_hikashop/classes/product.php" and replace
'manufacturer_id', 'page_title', 'url', 'meta_description', 'keywords', 'alias', 'msrp', 'canonical',
By
$removeFields = array(
'manufacturer_id', 'page_title', 'url', 'meta_description', 'keywords', 'alias', 'canonical',
And then you should be able to edit the retail price on the variants.
Regards,
