Default groups missing in site permissions

Question

The site members and site visitors group is missing under site permissions in SharePoint online. Is there a way to get those back?

Hi @Joshua Renoe , welcome to Q&A forum!

Did you delete groups by mistake? Under normal circumstances, a newly created website will have these default groups.

=========================================================

If you want to rebuild the default groups, please follow the steps below:

1. Go to the affected site, click the gear and select Site settings.
2. Select Site permissions under Users and Permissions.
3. Check which default member group is missing in this page. ( Owners, Members, Visitors)
4. Modify the URL of this page to /_layouts/15/permsetup.aspx.
   
5. Create a new group for the missing default group. (You can also use an existing group.)
6. Save the changes.
