-- url of the page with the problem -- : madebyleah.uk
-- HikaShop version -- : 4.22
-- Joomla version -- : 3.9.14
-- PHP version -- : 7.3.13
-- Browser(s) name and version -- : Chrome 79.0.3945.117
-- Error-message(debug-mod must be tuned on) -- : 0
Error: 0
Cannot pass parameter 3 by reference

Suddenly, I'm getting an error on my website www.madebyleah.uk when I add something to the shop and checkout - its saying that I need to login (which is correct, but normally it comes up with a nice Hikashop message, not this ugly system generated one (which is putting people off and they are leaving the site). Could you advise please?

Hi,

Please activate the "error reporting" and "debug mode" settings of the Joomla configuration and try again. The error message should display with more debug information allowing us to better understand the situation. Please provide a screenshot of all the information of the error when you do that.

Hi there, and thanks for your response.

I already currently have the 'error reporting' set to 'development': and 'debug' set to 'yes'. 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.

Hi,

Then please check the PHP error log of your server.
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.

Hi Nicolas, thanks for that!

I thought I'd start with the easy one first - switching the templates. Which brought up the following:Please let me know if this helps or whether I still need to search for PHP errors.

Hi,

Thanks.
That helps.
Edit the file /components/com_hikashop/views/checkout/tmpl/login_form.php and change the 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:
<?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.

Can't see where the 'legacy setting is in the checkout configuration, but the replaced code seems to have done the job!
