You can see the errors live for yourself, also the screen grab of what I see on the image I attached on the original post. So, as originally sated "Error: 0 Cannot pass parameter 3 by reference" is the only error message I can manufacture. If I'm doing anything wrong or missing something, please let me know.

You should have there a Fatal error message with the text "Cannot pass parameter 3 by reference" in it with also the file path and line number where the error happened. Please provide the full error message. Also, what you can try is to switch to the default Joomla template and see if the error message contains more information on that page with the default template.

Could you advise please?")* Hi, Thanks. That helps. Edit the file /components/com_hikashop/views/checkout/tmpl/login_form.php and change the code: Code: <?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'); ?> to: Code: <?php $params = null; if(isset($this->params)) $params = $this->params; echo $this->cart->displayButton(JText::_('HIKA_LOGIN'), 'login', $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'); ?> and that should fix the problem. We'll add the patch on our end. This actually comes from the fact that you're on PHP 7.3, and that you're using the legacy (old) checkout. So I would recommend to turn off the "checkout legacy" setting of the HikaShop configuration.
