How to edit a user's profile page & fill out empty fields

If users did not fill out all the fields in their profile, an admin or editor can edit the user's profile and complete the information of the empty fields through the user Profile form.

To edit the profile, go to wp-admin > Users, find a user whose data you want to edit and hover your mouse over the user, then click the View profile link.

You can also find a user in the member directory on the website front side and click the user name to view the user's profile.

Once you are in the user's profile, click the gear icon ⚙ to see the profile actions menu, then click the Edit Profile item.

You can now fill out the empty fields, edit or add information to the user's profile page.

Click the Update Profile button to save changes.

You can add and edit fields in the Profile form via the Form Builder. Go to wp-admin > Ultimate Member > Forms > Edit to edit the Default Profile form. This article will help you on how to add fields in a form. Make sure to add all fields that you want to display. This will allow you to view and edit these fields in member profiles.

On the right sidebar of the Profile form, you can see the Customize this form section. You can use the Make this profile form role-specific setting in this section to make a specific profile(s) if needed. See doc Unique profiles for different user roles.
