I use the hikashop starter. i found that when the user login the websites, there is not 'Log out' button so that they can leave their session and stop buying something. I read some solutions online.

First one, i add a new menu item called "Logout" and it is a external link with the parameter of 'index.php?option=com_user&task=logout'. however, it doesn't work and the user is still keeping online.

Second one, I add a custom html and put it under the menu, and its name is also 'Logout' and edit it into a link with the same parameter but 404 error happened when click it.

I do not how to add 'Logout' button into Hikashop system and I just put it somewhere so that it can let the user log out (destroy their session). If you know that, please give me some detailed steps. THANK YOU

Hi,

The logout is a Joomla issue, not really related on HikaShop.
What can be done is create a login Joomla module, adn restrict it to only registered customers group, this way it will only display a logout button.

Thank you. I solve it according to your method.
