social media icon in header not imaging after last WordPress enfold child

Hi guys,

I updated the function-set-avia-frontend.php file as you suggested on all my enfold installations where the social medias icons stopped imaging on the last wp update. On one however I installed a child theme after the fact. The other installations have child theme as well and the php update worked. In this case after the child install it does not, even after reinstalling the theme. After reinstalling the theme I noticed the social media icon was working, without reuploaded that php file. I tried making the same path in the child theme folder and placing the php file there but that didn’t work. Ani ideas?

Thanks
