Class 0 does not exist ERROR!

-- HikaShop version -- : 2.4.1
-- Joomla version -- : 3.4.1
-- PHP version -- : 5.0
-- Error-message(debug-mod must be tuned on) -- : Notice: Undefined property: stdClass::$list in /home/feeolond/public_html/plugins/system/jvnewsletter/jvnewsletter.php on line 80

Have an issue with HikaShop registration.

When the registration form is submitted an error message pops up "Class 0 does not exist"

I attached what the problem is. Please guide me through this issue.

Hi,

I'm sorry but we do not have any "Class ... does not exist" message in HikaShop (or HikaMarket).
I see that you have a notice from your system plugin "jvnewsletter" ; please be sure that this plugin is not pushing the Joomla error message (or another plugin).

Regards,

PS : I think you're using HikaShop 2.4.0 ; HikaShop 2.4.1 has not been released, yet.
