I’m having trouble using these icons.

On your demo under the “Branding Services”

I believe in the theme, this is the code that comes with below:

Also adding to it, I am using this that came in the documentation; https://www.livemeshthemes.com/support/wp-content/uploads/icon-sprites/index.html

to guide myself which icons are which.

[wrap class=”row first”]
[one_third]
[icon class=”icon-heart”]
<h3>Timeless Design</h3>
Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet accusam takimata sanctus.
[/one_third]
[one_third]
[icon class=”icon-cloud-upload”]
<h3>Easy Configuration</h3>
At vero eos et accusam et justo duo dolores et ea rebum. Lorem ipsum dolor sit amet kasd gubergren, sea takimata.
[/one_third]
[one_third_last]
[icon class=”icon-euro”]
<h3>Precise Targeting</h3>
Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut duo dolores.
[/one_third_last]
[/wrap]
[wrap class=”row last”]
[one_third]
[icon class=”icon-speaker”]
<h3>Huge Analytics</h3>
Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut quis nostrud.
[/one_third]
[one_third]
[icon class=”icon-bars-alt”]
<h3>Tuned to Perfection</h3>
Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet accusam nostrud exerci.
[/one_third]
[one_third_last]
[icon class=”icon-pin2″]
<h3>Expressive Design</h3>
At vero eos et accusam et justo duo dolores et ea rebum. Lorem ipsum dolor sit amet enim ad minim veniam.
[/one_third_last]
[/wrap]
[/segment]

Now I’ve Kept the same code, just replaced some icon names such as [icon class=”icon-cloud-upload”] with [icon class=”icon-shield”] but nothing shows up, wondering what’s going on with that? Do I have an outdated icon index?
