By default, all users are part of the Users group. Administrators are also part of the Administrators group.
Depending on what you did, you should be able to remove the users from the group, and make sure that they are part of or added to their default group(s) as above.
Hi Brink ,
Yeah Brink , the link is good, and also i know this information already, but i want to reset the users group to default without navigating to a member tab and select the user because it take time, if i have a user account that belong few user group so i have to delete one by one.
I want a faster solution, so as my thread stated, reset the user group to default, if that possible.
