checkout page following user activation

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

When a user receives their email asking them to activate their account, the activation link does NOT take them back to their order. How do I fix this so that it does?

Hi,

It works fine on my end.
However, there was a bug with this a few weeks ago that we patched since then.
So I would first recommend to download again the HikaShop install package on our website and install it on yours. It will add the patch to your website. If you still have the problem, we'll need you to provide a link to the shop so that we can check on the situation.
