vitalik20 Hi
You can try opening this file: [your_site_root]/components/com_guru/views/guruorders/tmpl/mycourses.php
Remove this code (line 325-329)
<?php if ($nr_orders > 0) {
?>
<a href="<?php echo JUri::root() ?>index.php?option=com_guru&view=guruorders&layout=myorders&Itemid=<?php echo $Itemid; ?>&course=<?php echo $id; ?>"><?php echo JText::_("GURU_VIEW_ORDERS")." (".$nr_orders.")"; ?></a>
<?php
} else {}?>
