I have a multi site enabled word press site. I want to restrict the users registered in main site should not access sub site. Please help me how to achieve this.
At the beginning I used Multisite User Management plugin to give both site users can access both main site and sub site. Because of this there may some additional information may be inserted in database table. I need to find out that. Now I want the main site users should not access subsite. In subsite I will create users in admin panel. Any help would be appreciated.
