Icons Not Showing on all pages

I installed your Social Media Widget a while back and it worked fine. But for some reason all of a sudden my icons are not showing on a couple of pages. One of the pages is the home page which is critical. Website is http://www.weddingclocks.com . They show on the other pages. Any ideas as to why they wouldn’t be showing up.
Thank you for your help.
