Font Icons broken after moving to development copy

Hi there,

I’ve recently duplicated my site to a dev server (you know, so we don’t end the world), but it seems like the font icons used for social, back to top, etc. are missing and display empty boxes.

Here’s the (working) live site example: https://dl.dropboxusercontent.com/u/4966805/sharing/viai/theme/live.png

Here’s the (broken) dev site example: https://dl.dropboxusercontent.com/u/4966805/sharing/viai/theme/dev.png

I’ve changed the URLs in the backend and through phpMyAdmin, as well as uploaded the theme from scratch. In both sites I’m using a child theme. Any help would be greatly appreciated :)
