If you are using the Enfold theme for your WordPress web site, after updating to WordPress 5.3.1 you may have noticed that your social media icons disappeared.
The issue appears to stem from the WordPress 5.3.1 security and maintenance release which may be preventing the rendering of the icon font script used to display said social media icons. But this is just a guess.
Luckily, the Kriesi Media development team at Enfold have addressed the issue. The solution to the problem will be included within the next Enfold theme release which is expected sometime after the holidays. In the meantime, they have provided us with a way to patch the issue and restore the social media icon font functionality.
