Hi there,
You just need edit the listing view of order (Display>Views) and remove these lines of code:
<th class="hikashop_order_modified_title title">
<?php echo JHTML::_('grid.sort', JText::_('HIKA_LAST_MODIFIED'), 'b.order_modified', $this->pageInfo->filter->order->dir,$this->pageInfo->filter->order->value ); ?>
</th>
<td class="hikashop_order_modified_value">
<?php echo hikashop_getDate($row->order_modified,'%Y-%m-%d %H:%M');?>
</td>
That will delete the last modified column. About the payment method, just add this where you delete the first code:
<th class="hikashop_order_modified_title title">
<?php echo JHTML::_('grid.sort', JText::_('SHIPPING_METHOD'), 'b.shipping_method', $this->pageInfo->filter->order->dir,$this->pageInfo->filter->order->value ); ?>
</th>
and this where you deleted the second code:
<td class="hikashop_order_shipping_value">
<?php if(!empty($row->order_shipping_method)){
if(!empty($this->shippings[$row->order_shipping_method])){
echo $this->shippings[$row->order_shipping_method]->shipping_name;
}else{
echo $row->order_shipping_method;
}
} ?>
</td>
It should work
