In the header of the template, there should be a stylesheet referencing Font Awesome. In the link tag, it should start with something similar to

Code:

href="//...

pre-pend http: to the front like thus

Code:

href="http://

I'd give a more in-depth explanation, but I'm on mobile at the moment, my solution is purely based on guesswork.

EDIT: Got home and had a look, it seems like my solution is irrelevant, PM me the files you've got and I'll be able to help you.
