Hi,
I searched for hours in the forum but I could not have any hint to solve my issue.
I set up a couple of products and the payment/shipping options (paypal or COD, manual shipping), in a correct way (as far as I can see). The checkout flow is All seems to be ok: payment, shipping, cart, address (registered and logged in). But when I click on "confirm" the same page reloads without completing the process. Tried various option on the configuration, and finally I upgraded the from starter to essential. Same result. Apparently no errors (the template has the message position).
Can you please help?

Hi,

I would have said that the issue is that the shipping methods are not found and that the template is not displaying the error message.
But if you say that it's not that, then I don't know.
We would need to look directly at your setup and your checkout to be able to tell you what the problem is.
One thing you can try is to turn on the debug mode and error reporting options of the joomla configuration and try again. That might display an error message with information on what's going on. Otherwise, we would need that you put a copy on your website online for us to assess the situation.

Hi,
now you can test the component at this address : farmaciacasa.marcoalfano.eu/index.php/hi...for-products-listing

If you need to access admin panel, I'll create an acount for you and send credentials via private message or email. Please let me know.

Hi,

That's very strange. I checked what I could on your backend but didn't find enough information. Could you allows the user account you provided to access the joomla configuration and the HikaShop configuration because at the moment I cannot access them ?

Hi,

i made your accont (nicolas) a super user.
Thank you
Marco

Let me know i f I can help you in other ways (ie send conf file etc.)
regards
Marco

Any news?...

I couldn't find any clue in your settings which look correct.
Could you please provide a FTP access to the website via our contact form so that we can put some traces in the code ?

I Just sent the credentials via contact form.
Waiting for news.
Thank you
Marco

We found the issue. It was a bug with the shipping method handling after the improvements we added for the support of the multi shipping.

The solution was to change the line:
if(substr($shipping, -$key_lng) == '_' . $group_key) {

to:
if($several_shipping && substr($shipping, -$key_lng) == '_' . $group_key) {
