Hi,
The '<br>' is not normal, please check the HTML generate code of the configuration page in order to see the action in the "<form>" element.
But, the url is hard coded in the HikaShop view, it is strange that a "<br>" is added.
The code in the HikaShop config view :
<form action="index.php?option=<?php echo HIKASHOP_COMPONENT ?>&ctrl=config" method="post" name="adminForm" id="adminForm">
