User Registration does not work

-- HikaShop version -- : 3.1.1
-- Joomla version -- : 3.7.3
-- PHP version -- : 5.3.29
-- Browser(s) name and version -- : Chrome 60

If a user does the registration he gets a mail with his information and the link to activate.
After clicking the link the login doesn't work.
But the user is shown in the user-table in backoffice.
Is there an ability to check weather the user activation has worked?
Because the error says the account is "not active or blocked"
Somebody ideas to deal with it?

Hi,

I would recommend you to check the settings of the Joomla user manager. There, if you configured the validation of user accounts to require an admin approval, even if you click on the activation link, you'll only be able to use the account after the approval of the admin.
Also, you can deactivate the activation email altogether with the settings there and the user will automatically be logged in after the registration.
