Font Awesome icons are not working, I have included all required files [closed]

For seekers of missing font-awesome icons, I have collected a few ideas:

Assure you use a correct link to the CDN, such as:

<link 
  href="http://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.3.0/css/font-awesome.css" 
  rel="stylesheet"  type="text/css">

If your page uses HTTPS, do you link to the font-awesome CSS using HTTPS (replace http:// with https:// in the link above).
Double check that you don’t have AdBlock Plus or uBlock enabled. They might be blocking some of the icons.
Reset your browsers cache. (On Chrome do a looong click on the reload button and select Hard Cache Reset)
Assure that the  or  element you use, uses the FontAwesome font family. For example, it must not just
```

```
but
```

```
It won’t work if you have something as the following in your CSS:
```
* {
 font-family: 'Josefin Sans', sans-serif !important; 
}
```
If you are using IE8, are you using a HTML5 Shim?
If this doesn’t work, there are further Troubleshooting Ideas on the Font Awesome Wiki.
