Social Media Buttons on Header and Footer Not Working

We have a website with social media buttons on the header and footer. We’re having separate problems with each.

HEADER: We have a social media bar with Facebook, Twitter, LinkedIn, and an Email button. The links work fine, but only the Email icon is showing up. The boxes turn the correct colors when you hover over them, but there is no icon.

FOOTER: The footer was created as a page and then set in Enfold under the “Set page to appear as footer and socket” setting under the Theme Options. It appears and is visually correct, but the links don’t work correctly. The links are set on the page where the footer was built; each button has a specific link to go to, but when you click on them on the front end of the website, they go to the CONTACT US page we built separately.

Here’s a link to the site: http://animalcaretrustusa.flywheelsites.com/

Anybody have any ideas on how to remedy this?

Thank you
