Hello,

I need to set the display name for users only to username – any other option can’t be active. Is there any way I can get that done?

this (surprisingly) is not easy within bbpress.

You would do better to force worpdress to have display name as username eg

The technique that Robin is recommending works for me, with the caveat that if you happen to be using memberpress and BuddyPress also, you may run into some other issues. If that happens to be the case, please post again.

Hey, thank you for that answer. I combined it with

<script>
     jQuery( document ).ready(function() {
      jQuery('#nickname').prop('disabled', 'disabled');
      });
</script>

And it worked as I needed 🙂
