I’ve inserted the CSS, and the footer element is now appearing, but the inline block elements (i.e. those appearing in the WPBakery blocks on the page(s) aforementioned) are not being shown, irrespective of the circles for the Social Icons being shown.
Please contact the plugin support. We do not know the build of the plugin and cannot fix that more over fixing plugins is not covered by our support. Perhaps you can find an equivalent plugin which is compatible with WP Bakery page builder.
