Hi,
I've check the code and the issue seems to come out in the file componente/com_hikashop/checkout/tmpl/login.php
At the line 53 at
$this->loadTemplate('form')
start the issue.
It seems to come from login_form.php
at line 187
<?php echo $this->cart->displayButton(JText::_('HIKA_LOGIN'), 'login', @$this->params, '',' var b = document.getElementById(\'login_view_action\'); if(b) { b.value = \'login\'; } document.hikashop_checkout_form.submit(); return false;','', 0, 1, 'btn btn-primary'); ?>

but I'm not be able to understand what's matter
