I found an error every time I access add to cart button from my homepage.
it shows : Notice: Undefined property: stdClass::$link in \Eric\web\root\main\components\com_hikashop\router.php on line 56
I am trying hikashop on my local machine: http://localhost/main/
/main/ is joomla folder
i activate joomla URL Rewriting and all hikashop SEF URL options
please help...

i found one interesting after looking at the console from my firefox
this is the url when checkout button is doing just find and this is the url when checkout button shows error so, i notice the "/category/" is missing when checkout button shows error...
how do i solve this?

Hi,

Replace the line:
if(!empty($menu) && $menu->link =='index.php?option=com_hikashop&view=checkout&layout=step'){

by:
if(!empty($menu) && !empty($menu->link) && $menu->link =='index.php?option=com_hikashop&view=checkout&layout=step'){

in the file components\com_hikashop\router.php and that will remove that notice message.

Thank you for your reply, Really appreciate!
I will try your suggestion
