CUNY Academic Commons

We are using Lucid for https://jtds.commons.gc.cuny.edu/ (site is still in development, but I can grant admin access for visibility). The theme has a place for social media icons in the header to the left of the search bar. We were using the FB icon and included a link on the theme settings page, but the icon disappeared a couple of days ago for some reason. We disabled all plugins in case there was a conflict, but that also doesn't seem to have an effect. The theme is from Elegant Themes, so we have no way of downloading or troubleshooting theme files.

Thank you,
Jessica
