The custom roles are made by the theme we bought (https://workscout.in).
The odd thing is just that it used to work and nothing changed as far as I know.
Those fields (Facebook, LinkedIn etc. were added by myself, but are indeed not necessary). However, they are not displayed at the add new user menu and this displays the same things as your screenshot, so nothing wrong there. Anything else I could try?
Is there another way you know in which we can add users?
Thanks!
