I have Already done below steps :-

3. I have verified and checked path of font-awesome and permission, everything is correct.

Answer 1

Got it Working, New Font-awesome also asks to add fa too with other icon class.

Example :-

<i class="fa fa-truck"></i>

Missing fa will break the icon and will not work.

Friendly advice, if you are using font-awesome icon heavily, do not update without backup. They have renamed and removed few icons.
