In the newest version 4.74, the icons have disappeared from bottom section of the website, as well as the up-down arrow. Is there a bit of CSS I can install to retrieve/relink the images?
Please try this to see if it helps: https://kriesi.at/documentation/enfold/icon/#icons-are-showing-as-rectangular-boxes-. If not then please try to load the fontello icon font from your actual site, not from a CDN like you are currently doing.
