I am not able to get User Registration to work properly using a frontend form from the Craft Docs (https://craftcms.com/docs/templating/user-registration-form).
Here are the particulars:
Craft Pro Version = 2.6.2791
Users > Settings has the ‘verify email addresses’ and ‘allow public registration’ boxes checked, and a default User group selected
I specified a redirect in craft > config > general to 'activateAccountSuccessPath' => 'registration-success',
The form submits and the user is created, but no verification email is sent and the user is not assigned to the group I selected in User Settings. If I manually send a verification email, following the link causes the user to be verified, but still not added to any Group. Further, the user is redirected to http://sitename/dashboard, despite having a redirect set in the Config > General file.
I tried this on two different Craft sites, each on different hosts (one of which is Arcustech) and both of which are running the latest Craft release (2.6.2791).
