We'll create fresh WordPress site with DW Block User Account installed. You have 20 minutes to test the plugin after that site we'll be deleted.
If you have a large website with a lot of users or a small website with few users, and in some cases, such as user abuse or other reasons, you can block user, with this plugin. (user cannot enter to wp_admin.)
After blocking if the user is in his account, he will also be logged out.
