But I couldn't see the Private Messages buttons in the upper right corner.

It is hidden by default when there are no new private messages.

To make it appear, please do the following in this file:
administrator/modules/mod_messages/tmpl/default.php

if ($hideLinks || $countUnread < 1)
to
if ($hideLinks)

I trust if you are going to insist on this pointless change then you will be updating all the other instances in the admin. There is a valid reason to use a generic class in the frontend but none in the admin

[Quy]

Nope. There are only 2 instances of fa- in the backend, thus, this PR. The rest are icon-.

[brianteeman]

Search again

[Quy]

Well this PR makes these icons consistent with the other icons in the header. I am blind to what you are referring to so please enlighten me.
