This tutorial assumes you are already logged in to your Joomla admin panel
Joomla does not allow you to block or delete a super administrator directly, so you will first need to change the user's group
1) Click Site
2) Then User Manager
Let's see what happens when we try to delete a super admin
3) Check the box next to the user
4) Then click Delete
Joomla will give you an error message
Now let's change the user's group
5) Select the user
Scroll right
6) Click Edit
7) Choose a new group for the user
Scroll right
8) Click Apply
Now that the changes have been applied, we can either block or delete the user. Let's see how to block a user first
Scroll down
9) Check Yes next to Block User
Scroll up and right
10) Click Save
The user has now been blocked as is indicated by this red icon
Now let's see how to delete a user
11) Check the box next to the user
