Hello hika team,

I am currently messing around with hikashop 2.3.1, in the sense of just trying out some options. No code modifications, no custom plugin shenanigans etc.

Environment is clean joomla 3.3 install with only hikashop business 2.3.1 installed and the t3 template framework.

In the hika configuration, "Login & registration" is set to:
Login: no
Display: all in one
registration: guest
confirm mail field: yes
ask address on registration:no

Case = oder product ->checkout-> enter existing email -> confirm existing email-> click next

The system correctly outputs "error:email address already used", however I always have error reporting on and the following notice follows:

( ! ) Notice: Trying to get property of non-object in D:\wamp\www\J3.3\administrator\components\com_hikashop\classes\cart.php on line 279

Hello Drago,
Can you download the last Hikashop version through our website, install it and test it again ?
Thanks.

EDIT - The error is only present if the checkout process is set like this:
Step1
Login
Address
Cart
Payment
Fields
Staus

Hi,

Could you give us the corresponding code line in that file ?
It seems that I don't have the same version than you.

Hi,

Here it is

if(!$app->isAdmin() && !empty($cartInfo->cart_id) && $currUser->user_cms_id != $cartInfo->user_id && $session->getId() != $cartInfo->session_id)
			return false;
