How to allow a user to edit all entries
This will allow an user to edit and delete any entry, not only their own, so make sure you want to do this!
1. Install and Activate the Members plugin
2. Go to the Users "Roles" submenu
3. Click "Add New" button next to Roles
4. Give the new Role a name
In this example, we've named the role GravityView Moderator.
5. Add "gravityforms_edit_entries" capabilities
There are a lot of capabilities to choose from. At the very least, you're going to want to allow the user to have the
read capabilities. If you want them to also be able to delete entries, you'll want to enable
gravityforms_delete_entries as well.
6. Add the role by clicking "Add Role"
Now you've got the Role set up, we need to assign the new role to the user.
7. Go to the Users page
8. Click the user you want to be allowed to edit all entries
9. Under "Role", select the newly-created "GravityView Moderator" role
10. Click Update User to save the User's updated role
And that's it!
Now the user will be able to view, edit, and (if you enabled it), delete any entry.
