Question Author missing author link?

Note sure if there was an update that removed the profile link to the “Questions” author, but it is really important to have that feature. Can that be restored? This is on a members-only website, so the site is not open to the public. I am getting this error all over the dashboard:

[Q&A] After Visitor Submits a Question setting requires registration of the visitor, but your website is closed to registrations. You may consider to fix this using plugin settings or WordPress settings.

Can we disable that message?

Thanks,
