Social icons have disappeared from the header/footer of my site (https://www.simpleltc.com/). Circles still appear when mousing over, but no icons. In the footer, the colored circles still appear and links work but with no icons in them. In Chrome a blank box is visible in the icon. In Explorer no boxes appear.
Previously your support team suggested it was likely a plugin conflict. I tested every plugin individually by deactivating and also tested deactivating all third-party plugins together. Nothing seemed to affect it at all.
Please advise how to troubleshoot this. Thanks!
