Footer disappeared since last theme update

Since updating to the latest version of the theme, the footer content was wrong. It was showing meta information, helpful links, categories, and site pages, etc. In another thread I saw that copying the footer.php from the parent theme to the child theme would fix it. Since doing so, the footer completely disappeared. I upload the previous child theme footer.php, and for a while it showed the incorrect content again. But in the last hour or so, the footer has vanished again. The Private Content shows my credentials. Thanks!
