Hi Tuan,
For plans with fixed expiration date there is no table row similar to Duration. I have to add it thru overrides (second plan on screenshot). I would be great to have it by default.
Here is the code you need to add in ./common/plan_information.php around line 103, between DURATION and PRICE sections:
Code:
?php if ($item->expired_date && ($item->expired_date !== $nullDate))
{
?>
<tr>
    <td><?php echo Text::_('OSM_EXPIRATION'); ?>:</td>
    <td>
        <?php 
            echo $item->expired_date;
        ?>
    </td>
</tr>
<?php 
} 
?>
 
and OSM_EXPIRATION constant as well.
Thanks!
