Please help me. I have a problem about user group in joomla 3.2.1. I created a new user group(name: Hoa Si) then i create a new user(abc) for Hoa Si group. But i can not login with new user(abc) on front end. But if i change the new user(abc) to any group in user group then login successfull to front end. New user group create: USER GROUP MANAGER -> NEW -> Group Title *: Hoa Si ; Group Parent *: Public. Thanks advance!
You need to change the Group parent to registered (or any other than Public, Guest). As users from Public usergroup are not allowed to login at website.
Or you need to change the permissions of your newly created usergroup.
It is not only creating a new user group, but also what Permissions and access the users in a user group will have. If you have set your user group as a child of the Public user group, then it won't have Site login permissions.
You should either go in the Global Configuration -> Permissions and assign to it the right permissions, "Site Login" and only for simple front-end login (registered users), or set this usergroup as a child of the Registered user group, in order to inherit its permissions.
