hello, I have searched many times in this forum with various keywords but did not find it.
Is there a way to restrict registrants from using certain usernames, nicknames or display names? for example the username "admin, administrator, etc." because there are my registrants who still register using that username even though there are regulations.
WPforo uses WP core for registrations, perhaps a plugin such as this might work for you: https://wordpress.org/plugins/restrict-usernames-emails-characters/
Probably because the registration form is going through WPforo. Perhaps test it with the WP native registration system.
