Icons in Featured Texts

My small business website has come a long way since I first copied and pasted the “Homepage Example” script in the documentation. Unfortunately whenever I try and change the copied icons from the column shortcode, it goes from showing screen, cog, and profile icons, to showing no icons; only titles and text.

Please help and thank you in advanced.

Here is the shortcode snippet I’m referring to.

[column width="1/3" position="first" ][feat_text title="Clean & Modern Design" icon="screen"]Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.[/feat_text] [/column] [column width="1/3" position="none" ] [feat_text title="Easy Customization" icon="cog"]Whenever you find yourself on the side of the majority, it is time to pause and reflect.[/feat_text][/column] [column width="1/3" position="last" ][feat_text title="Responsive Design" icon="profile"]I am so clever that sometimes I don’t understand a single word of what I am saying.[/feat_text] [/column]
