[For 1.8] Square theme

[eNvy]

So to be honest... it's like my 3rd time with MyBB
and I'm making forum for a server network
However... I have an error... or it's just my stupidity 

I'm kinda missing icons....
Can you tell me how to repair it?

Go to ACP > Templates & Style > Templates > Square templates > Ungrouped templates > open headerinclude template

Search this line:

<link href="{$mybb->settings['bburl']}/images/square/font-awesome/css/font-awesome.css" rel="stylesheet" type="text/css" />

Replace with this:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css">
