Social Icons not displaying properly in Chrome, IE, Firefox on Enfold Theme

I have recently updated to the latest version of WordPress and updated the Enfold theme and all plugins. My social icons now appear as boxes with no picture on my homepage on Chrome, IE, and Firefox. In addition, the “Like us on Facebook” button on my Contact page also shows a square instead of a Facebook “f”. The Layer Slider on the homepage is also displaying with squares instead of arrows left and right. I have seen at least one thread that shows this there is a social icon display issue related to the ad blocker in Chrome. That seems troubling since most users will be running ad blocker. Everything displays properly on Safari.

I appreciate any help you might provide!
