Joomla / Hikashop User Log In

-- HikaShop version -- : 4.2.3
-- Joomla version -- : 3.9.16
-- PHP version -- : 7.2

Can you point me to documentation on how to configure Hikashop User Log In / Log Out?

Hi,

The only login form in HikaShop is the one in the checkout. And there is no logout in HikaShop.
If you want a login / logout interface on your Joomla website, you need to use Joomla's features.
For example:
www.joomlashack.com/blog/joomla/login-and-logout/
And you also have the Joomla login module you can setup in the Joomla modules manager.
