Front Page Doesn't Show Correctly

Hello,
I’ve been using the perth theme for about 2 months. Everything was just fine until I attempted to link to another to another site from the Front page. All the icons will not show now just the text and I cannot change it back to what it previously looked like.

The default Perth Front Page is what my Front Page should look like not just text. can you please help with this issue asap?

Hi,

Please clarify which icons are not showing up? from which section on your website?

Best Regards,
